Crafts from the engine from a washing machine. How to connect the engine washing machine. Connection and start

A homemade master in the economy often have to do what manually is not always easy and convenient. A variety of machines come to the rescue. But for you need a device that will be in motion, for example, an electric motor. But asynchronous three-phase motors, although simple in the device are very common, but it is not always possible to find and buy condensers for him. Therefore, you can use. In this article, we consider the engine connection scheme from washing machine to the network for direct rotation and reverse.

What motors use in washing machines

Most washing machines use collector electric motors. They are convenient because they do not require starting and working capacitors, can directly connect to the network. In addition, the simplest revolver regulator can be bought in any electrical store.

The collector engine from the washing machine consists of:

• Rotor with a collector;

  Brush knot;

  Tacogenerator or Hall Sensor.

To measure the speed of the engine and their regulation are used as time as tacogenerators or lining sensors. They are not used for the usual start from the engine from the 220V network, but needed to work with complex revolutions regulators that support power on the shaft regardless of its load (within the nominal, naturally).

Connection scheme

Initially, the engines from the washing machine are connected to the network using the terminal block. If it was not removed before you - when inspecting the engine, you will see a similar picture:

Order The location of the wires may differ, but mostly their purpose is:

2 wires from brushes;

2 or 3 Wires from the stator winding.

2 Wires from the speed sensor.

Note:

If you have three wires from the stator, then one of them is the average output, used to increase the revolutions in the pressure mode. Then if you found that one pair of wires gives resistance higher than another pair, then connecting to the ends with a large speed resistance will be less, but the torque is higher. And if you choose conclusions with less resistance, then on the contrary - the turns are higher, and the moment below.

Depending on the specific model on the block, contacts of some protection, such as thermal and so on, can be displayed. As a result, for simply connecting to the network, we will need four wires, for example, such:

Recall that most engines are the collector engines with consistent excitation. What does it mean? You need to connect the winding of the stator in series with the winding of the excitation, that is, with an anchor winding.

To do this, you need one end of the stator winding. Connect to a network wire, the second end of the stator winding connects with a wire of one of the brushes, and connect the second brush to the second network wire, this connection scheme is shown in the figure below.

Reverse

In practice, it happens that for use in the wall it is impossible to secure the engine in another plane, then you may not be suitable for the direction of rotation. No need to despair. To change the direction of rotation of the engine from the washing machine, you just need to switch the ends of the stator winding and the excitation winding.

To the process of switching the direction of engine rotation, you need to use the DPDT type toggle switch. These are six contact tunnels, in which there are two independent contact groups (two poles) and two positions in which the average contact is connected either with one or other extreme contact. Its internal diagram is shown above.

Motor connection diagram from washing machine with the possibility of switching the direction of rotation and is shown below.

You need to solder the wires from the brushes to the extreme contacts of the table, and to one of the middle contacts the wire from the stator winding, to the second - the network wire. The second end of the stator winding is also connected to the network. After that, you need to solder jumpers to the free two contacts "Cross-Low".

Adjusting turns

Turns of all collector engines are easily adjustable. To do this, change the current through the windings. You can do this by changing the supply voltage, for example, cutting off part of the phase by reducing the active voltage value. This method of adjustment is called a system of pulse-phase control (Sif).

In practice, you can use any 2.5-3 kW to adjust the engine from the washer. You can use a dimmer for lighting lamps, but in this case, replace the simistor on the BT138x-600 or BTA20-600BW, for example, or any other with a 10 fold of the current reserve relative to the motor consumption, unless of course it is enough. Connection diagram you see below.

But for the simplicity of decision you have to pay. Since we reduce the supply voltage, we limit the current. Accordingly, power decreases. However, when the engine loads, to maintain the specified turnover, it starts to consume a larger current. As a result, due to the reduced voltage, the engine will not be able to develop the maximum power, and its turnover will fall.

To avoid this, there are special fees that support the specified revs to receive feedback from the revolutions sensor. It is those wires that we did not use in the considered schemes. It works according to a similar algorithm:

1. Check the specified number of revolutions.

2. Read the sensor values \u200b\u200band save them to the register.

3. Comparison of sensor readings, real revolutions with specified.

4. If real revs match the specified - do nothing. If the revolutions do not match then:

If the revs are increased - we increase the angle of the phase of the sew phase to a certain value (lower the voltage, current and power);

If the revolutions are lowered - reduce the sequencing angle of the Sif phase (increase the voltage, current and power).

And so repeats in a circle. Thus, when you load the engine shaft - the system itself makes it possible to increase the voltage of the engine supplied to the engine or reduce it when the load increases.

It is not necessary to rush for the development of such, there are inexpensive ready-made solutions. An example of such a device is constructed. An example of a connection scheme you see below.

Here signatures indicate:

M - output to the engine.

AC - connection to the network.

T - Connecting to the Tank.

R0 is the regulator of current revolutions.

R1 - minimal revs.

R2 - Maximum turns

R3 - to adjust the scheme if the engine is unevenly running.

Conclusion

Note that the collector, or as it is also called in the people, the brush engine from washing machines is quite high-breeding, in the region of 10,000-15000 rpm. This is due to its design. If you need to achieve small revolutions, for example, 600 rpm, use a belt or toothed gear. Otherwise, even with the use of a special regulator, you will not succeed in achieving normal operation.

The washing machine, like other household electrical engineering, after a period of operation fails and is no longer repair. Therefore, you have to acquire a new one, but where did you give the old car? Of course, you can simply be thrown into disposal as MBS. But this is the impractical hosts, because the design of this household equipment includes many useful elements that can be useful in the economy. Consider what you can do from the washing machine.

What details can be used

The washing machine is a rather complicated household equipment, which includes a plurality of individual elements. The more modern, the more in its design it includes details.

Elements of washing, which can still come in handy:

Important! If you understand the electronics, then you should not throw away the control unit, which includes a large number of semiconductor components that can be useful when repairing other electrical equipment.

Application of the working engine of the washing machine

Consider some homemade from the engine from the washing machine. Today, with the help of the Internet, many homemade craftsmen are gladly shared by their own inventions, in the design of which spare parts from old washing machines were used. Consider the most sought-after.

Making concrete mixer

When repairs in the apartment, a private house may need a small amount of concrete solution. Rent for such a purpose concrete mixer is too expensive. You can build such a tool yourself, for which the case is suitable from the old wash (except for the machine).

Manufacturing instructions:

Simple concrete mixer for operating conditions is ready. With this device, you can easily prepare a bucket of the solution.

Entry from the engine from the washing machine

The working motor from the old machine machine can be used for making their own electrical emery. This is done very simply - the sandpaper (sharpened) is installed on the motor shaft. Such a tool will be very practical in the country, since it can be molded not only knives, but also shovels, axes.

Cubezka, Grainrock

Those who have a small land plot contains householdIt does not hurt made with your own hands the grainbill, the bubble. If this goal is to use an electric motor machine machine, then homemade adaptation It will not work not worse than the factory equipment.

Make in household conditions the bubble is easy. In addition to the motor, you will need a housing of the top loading machine that can be found on scrap metal.

It is important to understand! The engine factor of the washing machine can be used to make a variety of different economic tools that require rotation.

Worker Motor Washing can be applied to manufacture homemade toughness.

How to connect a motor from a washing machine

If the owners of the old typewriter have ideas for the further use of the engine, the question immediately arises how to connect it to the electricity network 220 V.

To begin with, it is worth dealing with electrical schemeAfter that, the engine connection to the power supply will not take a large amount of time. You need to deal with wiring. Specifically, the wires connected to the stator, the rotor will be used.

How to choose the desired wires

Look at the front of the block with wiring - the first two wires on the left are most often the wires of the tanker, through which the herald motor revolutions are adjusted. They will not need them.

Then there is a red, brown wire of the stator, and behind them two wires (green, gray) connected to rotary brushes. All these wires will be needed to connect the engine to the power grid.

Important! To connect to the power grid with a power of 220 to the engine of the washing machine, the starting capacitor is not needed, and the motor itself does not need a starting winding.

Of course, in various models of erasing wires, the wires differ in color, but the principle of connection is similar. To deal with the wiring, you need to ring each wire using a multimeter. The device must be configured to measure resistance. Then one probe device is applied to any wire, the second probe is selected steam.

A quietly functioning tachogenerator most often has the resistance of about 70 ohms. These wires are recognized primarily, removed to the side. After that, the rest of the wires are nicknamed, divided by pairs.

Connect the engine to the network

When with wires already everything is clear, it is necessary to connect them correctly:

• In accordance with the scheme, the end of the stator winding should be connected to rotary brushes (it is recommended to make a reed jumper).
• It is necessary to connect with the power grid wire of the rotor brush, the end of the rotor winding. After serving the voltage on the wires, the motor will start turning the shaft.

Important! Motors of the washing machine are characterized by high power. To prevent injuries, you must be extremely careful. Therefore, before launching the equipment, the motor is recommended to carefully fasten to some basis.

Application of drum washing machine

The drum from the washing machine, made of durable stainless steel, can be used for a variety of goals in the farm. From it you can make with your own hands a lot of practical products, such as a barbecue or a roaster for a barbecue.

How to make a roar:

• it is necessary to disconnect the drum from the old erasing together with the shaft and pulley;
• install it up with a hatch on the wheel;
• brazier is ready.

The working part of the brazier can be slightly increased. To do this, you will need a Bulgarian with which the front of the drum located near the hatch is cut. Accordingly, it will be much more convenient to put firewood.

For your information! For the manufacture of kebabs, the drum is the perfect material, as it has a huge number of holes through which the air flow will evenly inflate coals, creating the necessary heat.

Do not throw out the washing machine that has spent your time, as it consists of a variety of useful details that will still be able to come in handy in everyday life, in the country. At the same time, various adaptations made with their own hands will help save. cash.

The engine is the heart of the washing machine. This device rotates the drum during washing. In the first models of machines to the drum, belts were mounted, which performed in the role of drives and ensured the movement of the container filled with linen. Since then, developers have noticeably improved this unit responsible for the transformation of electricity in mechanical work.

Currently, in the production of washing equipment, three types of engines are used.

Views

Asynchronous

The motors of this type consist of two parts - a fixed element (stator), which performs the function of the supporting structure and serves as a magnetic pipeline, and a rotator rotor, which leads to a drum. The engine rotates as a result of the interaction of the alternating magnetic field of the stator and the rotor. Asynchronous This type of device was called because it is not able to achieve the synchronous speed of the rotating magnetic field, and follows it, as if catching up.

Asynchronous engines are found in two versions: they can be two- and three-phase. Two-phase samples are rare today, because on the threshold of the third millennium, their production has practically stopped.

The vulnerable place of such an engine is to loosen the torque. Externally, this is manifested by a violation of the trajectory of the drum movement - it is swaying without fulfilling a full turn.

The undoubted advantages of asynchronous type devices are the simpleness of the design and simplicity of service, which is the timely lubricant of the motor and replacing the predicted bearings. The asynchronous engine works quietly, and it is fairly cheap.

The disadvantages of the device include large size and low efficiency.

Typically, these engines are equipped with simple and inexpensive models that do not differ in high power.

Collector

Collector engines came to replace two-phase asynchronous devices. Three quarters of household appliances are equipped with motors of this type. Their feature is the ability to operate both from alternating, and from DC.

To understand the principle of such an engine, briefly describe its device. The collector is a copper drum, divided into smooth rows (sections) insulating "partitions". The contacts of these sections with external electrical panels (to designate such sections in the electrician, the term "conclusions") is diametrically located on opposite sides of the circle. With conclusions, both brushes are in contact with the sliding contacts that ensure the interaction of the rotor with the engine, one on each side. As soon as any section is powered, a magnetic field appears in the coil.

With the direct turning on the stator and the rotor, the magnetic field begins to rotate the motor shaft clockwise. This happens due to the interaction of charges: the same charges are repelled, different things are attracted (for greater visibility, remember the "behavior" of ordinary magnets). Brushes gradually move from one section to another - and the movement continues. This process will not be interrupted until the network has a voltage.

To send the shaft counterclockwise, you need to change the distribution of charges on the rotor. For this, the brushes include in the opposite direction - to meet Stator. Usually, miniature electromagnetic starters (power relays) use for this.

Among the advantages of a collective engine is a high speed of rotation, a smooth change in the frequency of revolutions, which depends on the voltage change, independence from the frequency of electrical oscillations, a large starting point and compact device. Among its disadvantages, there is a relatively short service life due to the rapid wear of the brushes and the collector. The friction causes a significant increase in temperature, resulting in the destruction of the layer, insulating the collector contacts. For the same reason, an interetic closure may occur in the winding, which can cause the magnetic field weakening. The external manifestation of such a problem will be the full stop of the drum.

Inverter (inscoleton)

Inverter engine is a direct drive motor. This invention is a little more than 10 years. Developed by the famous Korean concern, it quickly gained popularity due to a long service life, reliability, wear resistance and its very modest dimensions.

The components of this type of engine are also the rotor and the stator, but the fundamental difference is that the motor is attached to the drum directly, without using the connecting elements that fail in the first place.

Among the undoubted advantages of inverter engines are simplicity, lack of details subject to rapid wear, convenient accommodation in the body of the machine, low noise and oscillations, compactness.

The disadvantage of such a motor is the complexity - its production requires high costs and effort, which is noticeably reflected in the price of inverter cars.

Motor Connection Scheme to Network

Modern washing machine

When connecting the engine modern device For washing to the network with a voltage of 220V, it is necessary to take into account its main features:

• it works without a launcher;
• to start the motor does not need a starting capacitor.

To start the engine, you should definitely connect to the network by the wire from it. The following are the schemes for connecting collector and uncoolette electric motors.

First of all, determine the "front of work", eliminating the contacts that go from the tahegererator and do not participate in the connection. They are recognized by the tester operating in the module. Fixing the tool on one of the contacts, another probe, find the pair of it. The magnitude of the resistance of the tachogenerator wires is about 70 ohms. To find a pair to the remaining contacts, call them in the same way.

Now go to the most responsible stage of work. Connect the wire 220V to one of the winding outputs. The second one is required to connect with the first brush. The second brush is connected to the remaining 220-volt wire. Turn on the motor into the network to check its operation *. If you did not allow mistakes, the rotor will start rotating. Keep in mind that with such a connection it will move only one way. If the trial starts passed without lining, the device is ready for operation.

To change the direction of movement of the engine to the opposite, the connection of the brushes should be swapped: now the first will be included in the network, and the second is connected to the winding output. Check the readiness of the motor to work described above.

Vitely the connection process you can see in the following video.

Washing machine old model

With the connection of the engine in the old sample machines, it is more complicated.

First, determine the two appropriate pairs of conclusions. To do this, use the tester (it is the multimeter). Fixing the tool on one of the winding conclusions, other probe, find the output, pair to him. The remaining contacts automatically form the second pair.

Washing machines with time wear out and fail. Most often, they are simply thrown into a landfill. However, in many cases, the details from the washing machine can be useful. There are many options for the second life of the electric motor. It all depends on the skills, opportunities and fantasies of the home master. In this article you will find out where you can apply the engine from the washing machine if it is in working condition. Consider what self-made from the engine from the washing machine can be made.

Electric motor for a grinding machine or emery

The purchase of the finished sharpening machine is not always possible, first of all due to the high price, and in this case, the electric motor from the washing machine or other equipment is literally irreplaceable.

A lot of effort requires the correct layout of the future unit, as well as a solution to such technical problemlike a grinding stone nozzle on the engine shaft. In many cases, it does not have a thread, and the diameters of the shaft and the holes in the stone do not coincide. The usual output from the position is the use of a special detail, which is necessary to be ordered separately in the Tokary workshop. This item may be called the flange, adapter, hub, etc.

The flanged flange should be embraced on the shaft and fixed with the help of a bolt. In addition, a washer and a nut with a carving, directed to the side opposite to the rotation of the engine shaft. Due to this, during operation there will be spontaneous twisting of the nut. Otherwise, the Nut will quickly promote and the stone flies.

If necessary, you can change the direction of rotation of the rotor. In washing machines are installed, therefore, it is enough to switch the corresponding windings, and the direction of rotation will change. To start the engine, a start-up coil will need. If it is missing, then there is nothing terrible in this: when the stone is a push in the desired side, the device will earn independently.

For the manufacture of a grinding machine, it is not at all necessary to use engines of high power. It is enough 400 W, and even 100-200 W. It should be paid attention to the number of revolutions per minute, which should not exceed 3000. Otherwise, the motor with too high rotational frequency can lead to the destruction of the grinding stone. Most optimal option It is considered an electric motor with 1000 rpm.

Operation of the homemade sharpening machine involves strict observance of safety regulations. First of all, it is necessary to provide a protective cover to protect the abrasive dust and small fragments. For this, metal is suitable, 2.0-2.5 mm thick in the form of a strip, rolled into a semir. In addition, the manufacture of a girlfriend will need, to ensure the work being processed.

Transformation of the electric motor from the washing machine into the generator

Many home masters are engaged in the manufacture of self-made generators using electric motors from household appliances, including washing machines. This task is conjugate with certain difficulties, primarily the technical plan. In no compulsory, the services of a qualified Tokary will be required in the first stage of work.

First of all, it is necessary to disassemble an asynchronous engine taken from a faulty washing machine. Then the core falls into the hands of the turner, which removes the layer of the element, 2 mm deep on the machine. Then in the core, the slit of grooves to a depth of 5 mm is performed, in which neodymium magnets will be inserted. The grooves are recommended to do after the acquisition of magnets when their dimensions are known.

After all the work, neodymium magnets must be fixed on the core. For this purpose, a pattern made of tin or other thin metal is made. Its dimensions should coincide with the size of the core and the width of the grooves, and it must accurately fit into the installation site of the magnets. Magnets are located on the core at the same distance between themselves and are fixed with glue. In addition to the distance, the angle of inclination of each element is of great importance. Deviations from regulatory sizes may cause stipulation, as a result of which the generator power is noticeably declining.

Cold welding is used to fill the gaps between magnets. At the end, the surface of the rotor is polished with emery paper, after which the device is fully assembled.

The assembled generator must be tested. To this end, you will need a small battery, rectifier, multimeter and charge controller. Connection occurs according to a specific scheme. The charge controller is connected to the two generator windings through the rectifier. Then the controller and the multimeter must be connected to the battery.

For a normal check, it is necessary to rotate the rotor of the electric motor. It is impossible to perform this operation manually, so you should use a drill or screwdriver. The tool is connected to the engine rotor, after which the rotation starts at a speed of about 800-1000 rpm. With a high-quality assembly of the generator, the output voltage is 220-300 V. The lower voltage indicates a poor-quality assembly of the rotor.

After assembly and check, the generator can be used. This will require the cost of energy required for rotation of the rotor. Can be connected to K. small engine internal combustion, for example, from chainsaws or a motorcycle. but this method Requires the acquisition of an energy source. Therefore, other options are recommended, relatively inexpensive and environmentally friendly, associated with the use of wind or water energy.

All homemade masters must remember that the electric motor from the washing machine can be converted into a generator, no more than 5 kW. Typically, such devices are produced on average 2 kW sufficient for 1-2 rooms or baths. So it will not be possible to completely replace the electrical network with a homemade generator.

Engine lathe from washing machine

The engine from the washing machine is ideal for the manufacture of a small lathe on the tree. The basis of the design serves as a frame that can be made from a corner, profile pipes and other primary materials. The dimensions of the frame are within 100 x 20 cm, with possible deviations in one direction or another.

The electric motor is quite suitable from the old washing machine, perhaps even from Soviet times. For example, Vyatka-automatic was equipped with an asynchronous motor with two speeds by 400 and 3000 revolutions per minute. Connection can be performed in all known schemes, including using the capacitor.

The engine mounting system to the frame is performed individually. The most important thing is that the axis of the engine is set up parallel to the reference design. This can be done using the washers that, if necessary, put on the points of the support. Front grandmother is fixed on the pulley of the electric motor. The rear grandmother and guides are also made from remedies. The axis of the backstone should be parallel to the frame and the front grandmother, that is, it is necessary to perform its center.

An important detail is a girlfriend that performs the support function for the cutting tool. It is necessary to ensure its movement along and across the beds, as well as reliable fixation during operation.

Electric motor for woodcover

The basis of the structure, as in the lathe is the window. It is made of metal profile or square. The obtained platform will consist of two zones - power and working. The power side is designed to install the electric motor. It must be securely fixed, since the main load falls on it.

In the same zone there is a motor control unit. To accommodate electrical components, a dielectric plate is provided, and they themselves should be placed in a plastic case. The work area is made in the form of a table. A steel sheet is used as a material, 2-3 mm thick. On the border, the pedestal is mounted conditionally separating both zones, on which the colon-cone shaft is fixed. This item cannot be secured directly on the engine shaft.

For the cone shaft, its own support on bearings is equipped. In order to compensate for the jerks and creating a torque, the flywheel is recommended on the shaft.

After assembling the entire design, you can start connecting the electric motor. Most often used asynchronous motors. In the old aggregates of this type, a separate winding is provided for startup. To determine it on the engine, you need to alternately measure the resistance on each winding alternately. The desired winding will have a higher resistance. It directly participates in the creation of the primary torque in the desired side. If necessary, change the direction of rotation of the shaft, the point of connection of the startup is vary in places.

Modern electric motors are launched significantly easier. You can use the usual household apparatus to turn on and off.

Washing Machine Concrete Machine

Concrete mixer is necessary in the farm, especially in private and country houses. However, the concrete mixers are quite expensive, so one of the solutions to the problem will be the manufacture of concrete mixers from the remedies. The washing machine is best suited, and not only the electric motor, but also the case itself.

The base should be reliable so that the container in the process of rotation does not fall. From this completely depends the duration of the operation of the unit. An unstable base can lead to a drop in capacity and failure of other elements. Metal design is considered the most suitable. If desired, it can be equipped with wheels. All parts and parts are connected to each other with bolts or welding. To install the electric motor, you need to provide special shelves with fastening holes. On the same shelf and the gearbox is attached, the pulley of which should be in the same plane with the engine pulley. Otherwise, the motor will experience overload.

The on and off of the self-made concrete mixer is performed using a batch switch. In most cases, the condenser is present in the inclusion scheme. Thus, reflecting on what self-made from the engine from the washing machine can be done, any home master in practice will make a device most of all necessary in the household.

From parts from a washing machine, regardless of its condition and type, you can make a variety useful devices and fixtures.

They can perform various mechanical work, as well as play the role of generators of free backup energy. For the manufacture of homemade with an electric motor, the housing, wiring and other parts will rise.

Variants of devices

Below is described what can be made from the old washing machine. These devices will be useful for farm, construction, gardening and repair.

The most common homemade is emery. Since the diameters of the shaft of the motor and the grinding stone are different, it will be necessary to make a consistent adapter. His role will play a piece of 20-centimeter pipe. At the end of the last one should make a thread so that it is twice as long than the grinding stone. Its direction should be the opposite rotation of the motor. This is necessary so that the grinding circle does not unscrew and flick.

Adapter should be fixed on the motor shaft. Then you will need to drill a hole there, and screw the bolt and the nut to finally fix the emery circle with the adapter. It remains to strengthen the homemade on the reliable basis.

Motor power from a washing machine is enough for a small lathe or drum-grinding machine. In the first case, you can slowly treat the cylindrical workpiece. For more reliable consolidation, apply a support that protects the motor from excessive side loads. In the second case, the cylinder is put on the engine shaft, which is hoping for grinding paper. Inside it should also be installed a steel bar, with which you can fix on the motor shaft.

The old washing machine of the activator type can turn into a small concrete mixer. This follows:

• Make a blade, for which it is necessary to cut out of 4-5 mm steel blanks, connect at right angles (in the form of the letter P), and cook.
• Attach the item to the activator place.
• Connect the engine to the network (see below).
• It will only be left to put the necessary building materials in the tank.
• The power of the motor in this case will be sufficient for small volumes.

You can also make a bubble. In addition to the engine, a drum will be required from the washing machine. You need to make two sharpened blades playing the role of knives. The drum is attached to the support frame with bolts. In its lower part, an outlet should be done. One blade with a knife is installed on the bottom, and the other is closer to the top. On the front of the drum, it is necessary to adjust the cover so that the feed is not figured on the sides.

Another possible homemade is a lawn mower. It will work at all worse than the factory. For its manufacture, you will need:

First, it is necessary to weld the square frame with the axes. Based on which it is attached from its lower side, you should do a hole for the motor shaft, and then fasten it. Of the longer pipes, it is necessary to make a P-shaped handle. A rubber casing is put on its horizontal part to be more convenient to hold. Wire with switch connected to the motor. If you plan to use wet grass to circumcise, then you need to carefully insulate all conductive parts.

Finally, the last device that can be made from the washing machine - this is generator. Asynchronous engine will require refinement. It is necessary to disassemble it, cut into the rotor of the grooves in which it is necessary to insert and glue with cold welding neodymium magnets. The working winding will need to be connected to the controller, which stabilizes and rectifies the current induced in it and provides a given voltage.

Such a generator will be able to feed the lamp or charge the battery. The rotor can be driven by drill, screwdriver, or a pedal mechanism. Other options are also possible.

Types of motors

In older washing machines, asynchronous electric motors were used. They consist of a stator with a winding and a cylindrical rotor, which is driven by a rotating magnetic field. They are distinguished by low noise, simplicity of construction, and enough high power. But also there are also cons - these are large dimensions and weight, complexity of smooth speed control, and low efficiency and torque. They also cannot work as a generator without alteration.

The most common are two-phase asynchronous engines . They have a working and starting winding. The first is directly connected, and the second is through the phase shifting capacitor. Currently, asynchronous motors in washing machines are not used.

The collector engine is used in all modern washing machines. Works on direct and alternating current. It consists of a stator and the rotor, the magnetic fields of which interact, with the result that the latter rotates. It is equipped with a collector through which the stress through the brushes is served on the winding. Advantages - high torque and considerable rotation speed, which can easily and smoothly adjust. Collective motors are also capable of working in a generator mode with external excitation.

The inverter engine is connected directly to the drum. It is characterized by a rather complicated design. This motor can operate as an effective generator if the manufacturer of the electric motor installed the magnets in the rotor, thanks to which a considerable force will be induced in the stator.

Connection and verification

You must make sure that the selected motor works. To do this, determine the conclusions of the windings using a tester or multimeter. To check the operability of the collector motor, you need to connect one cable wire with a fork to one brush, and the other to the winding output. Free conductors are connected to each other. If the engine is working, the rotor will start rotating.

Asynchronous motor is connected differently. First you need to determine the working and exciting winding. The first will have greater resistance. It is supplied directly to it, and to the exciting - through the phase shifting capacitor.
