Motor connection from a washing machine

Using parts from an automatic washing machine that has already managed to get rid of itself on the household is quite a common occurrence if the owner of the house is “with his hands”. And this is quite justified, because the equipment, even if it is completely unsuitable for operation due to the failure of one or several parts, has a lot of useful elements in its device. For example, we will consider connecting the engine from a washing machine for various tasks useful in the household in this article, because if the washing machine has served its purpose, then it is completely not a fact that the same thing happened with the electric motor.

Use cases:

• The simplest case is a tool for sharpening knives, scissors and other household utensils. This device can be made without difficulty if the motor is connected correctly and the grindstone is adjusted.
• If you started construction on a site, then a vibrator for concrete is just what can be useful at a construction site. Concrete shrinkage will occur many times faster. Some craftsmen adapted an electric motor to construct a vibrating table in the production of cinder block or paving slabs.
• You can use the electric motor for agricultural purposes. For example, to create a mill for grinding fresh grass. It can be fresh juicy animal feed, harvesting silage for the winter, or simply disposing of weeds.

Thus, the area of ​​use of electric motors is very different. The common feature of these devices is that the engine drives various mechanisms and nozzles.

Proper connection

Now about what is the correct connection of the electric motor from the washing machine? Keep in mind the following points:

• Starting is performed without a starting capacitor and starting winding.
• Two white wires will not participate in the connection. They can be used to measure speed.
• Red and brown wires are directed to the winding.
• Gray and green wires are designed to power the brushes.

Power Connection Algorithm:

1. Connect the first of the leads from the winding to a power source.
2. Connect the brushes to the next two pins.

Important! After that, it is advisable to test the electric motor for efficiency. Turn it on and, if you did everything correctly, the device will rotate in one direction with a characteristic noise.

Motor reverse

Now we need to solve 2 more problems:

• Rotate the motor in the opposite direction.
• Adjust the speed of revolutions.

You can solve the first question by swapping the connection of brushes. Test the unit again for performance. If everything is in order with the rotation of the engine, it means that you did everything right.

Important! To adjust the rotation intensity, you can use the room dimmer. But this device needs to be improved a bit, because its power is not designed to interact with the motor. Therefore, remove the triac from the idle washer with a radiator. Now it remains to unsolder the low-power part in the microcircuit and solder the triac extracted from the washer. This procedure requires a certain skill. So, if you think that your knowledge is not enough, ask the more knowledgeable person to perform these manipulations.But in most cases, the motor serves faithfully without regulating the intensity of rotation.

The engine from the old washer

If the model of the washing machine is outdated, then using its engine will be somewhat more complicated. You can find inputs and outputs using the tester, ringing the winding. Using the tester, look for the “working-starting” pairs. The resistance of the launcher is greater than the resistance.

Important! As with an automatic machine, a capacitor is not needed. This is because the motor has a starting winding. If you use a capacitor, then the motor simply burns out.

Connection order:

1. Apply a voltage of 220 V to the operating winding.
2. The same voltage (but for a short time) must be applied to the start button.
3. After the button is released, power is not supplied to the winding.
4. To reverse the motor, you need to swap the contacts of the winding.

Important! When the engine is running, it must be locked. The best option is stationary use. The motor rotates fast enough, so you must follow safety rules.

If the engine shows signs of malfunction, try to repair the damage immediately. Otherwise, all your schemes, ideas for its application will be useless.
