How to connect a single phase motor?

Single-phase electric motors designed for operation from 220V mains are used in many modern household appliances, such as refrigerators, washing machines, food processors, etc. These engines are equipped with two windings: starting and working, and also have three or four outputs .

In that case, if only 3 wires leave the case - the motor windings are already connected inside the case. If there are 4 wires, it is possible to determine the start and working windings with an ohmmeter. The resistance on the starting winding will be significantly higher than on the working one.

How to connect a single-phase motor to 220V?

After you have labeled the outputs of the windings, you can connect the motor to the network. For this you need:

Now you can solder the leads and connect them to the wire that supplies power.
