If you have an unnecessary washing machine motor, do not rush to throw it away. The electric motor is used in other areas of life and economy. If you know how to connect the electric motor correctly, you can get a machine for sharpening scissors and knives. Or make it the driving force of a concrete mixer.
We will tell you how to connect the engine from the washing machine with your own hands.
Self-connection methods
For the engine to work, it needs power. Independent connection to electricity consists in the correct connection of wires. Therefore, you will need a wiring diagram for the washing machine motor.
To work, you need stator and rotor wires. But how to find them? A visual inspection shows a lot of wires. How to decide which one you need?
Consider how to connect an electric motor with 3, 4 and 6 wires.
Look at the motor. There are two wires on the left side – they are not used. Often the manufacturer paints them white. For clarity, look at the photo below:
The orange arrows point to the red and brown wires. These are the stator leads. The blue arrows point to the wires leading to the rotor brushes. These four wires are needed to connect the motor from the washer.
Wire colors may vary from manufacturer to manufacturer. Therefore, use a tester for an accurate check.
Measure the resistance of each wire to find its pair. Strip the contacts and connect the tester probe to them. Record your readings. Next, ring all the wires in turn until each has a pair.
Step-by-step execution of work
Connecting the engine from the washing machine is not a difficult task. You will not need starting windings and capacitors, it is enough to know how to connect the connections correctly.
To do this:
- Connect the ends of the wires from the stator and rotor. Be sure to isolate the contact point.
- Connect the remaining two wires to a voltage source of 220 volts.
Be careful! During the connection to electricity, the engine will start (switch on) from the washing machine. However, it can vibrate strongly, so ensure that the motor is in a safe location in advance.
The connection was successful. If you need to change the direction of rotation, swap the wires leading to the rotor. See the diagram in the photo:
This launch option is suitable for modern SMA parts. How to connect an electric motor from an old washing machine? The work is more painstaking than in the first case. You will need a start relay and a momentary button.
- Set the tester to resistance measurement mode.
- Apply the probes to the motor windings, comparing the readings. You need to find paired windings.
It is important to understand that the working winding always shows less resistance than the starting winding.
According to this scheme, the asynchronous motor of the washing machine is connected:
Let us analyze in more detail how to connect the SMA motor according to the scheme. To do this, let’s decipher the conventions:
- SB stands for switch button. It allows you to connect the winding to the power supply.
- Software is a starting winding that allows you to create torque. You can coordinate it to one side.
- OB – working winding or excitation winding. Creates a magnetic field for rotation.
You need to apply electricity to the excitation winding. To do this, directly connect it to a 220 volt network. Short-term power is also supplied to the starting winding, only with the help of a button (SB).
Now you know how to turn on the motor (engine) from the washing machine. To start it, you need to press the button. The change in the direction of rotation occurs according to the previous principle – the wires are interchanged.
Use cases
A working motor from SM can be used for household needs. Decided to lay out the yard with tiles? Make a homemade vibrating table.
You will need one plate, fixed with movable parts to the base. Starting the electric motor from the washing machine will contribute to the movement of the plate. By releasing air from concrete, you can improve the quality of the tile, make it stronger and more durable.
You can also make a concrete mixer, only you will additionally need another tank. Inside the tank, metal blades are installed in the form of the letter “P”. The drain hole is closed. How to connect the washing machine engine to a homemade concrete mixer can be seen in the video:
If you are a little versed in technology and have a desire to do something with your own hands, then you will find a use for the motor. You already know how to start the engine from the washer, so get to work. Video on the topic will help you:
