Most often, household appliances use a 220V electrical network. Some devices work through this network directly, for some additional adapters are needed. In our article we will look at how to connect a 220 V electric motor.
A little bit about the standard connection
Asynchronous single-phase electric motor is easy to connect, because the voltage that it consumes is 220 V. Therefore, it just needs to be connected to a 220 V network. But, of course, such an electric motor has its disadvantage - this is the smallest efficiency. Therefore, we will try to connect a more powerful engine of 380 V. And those who want to learn more about 220 V engines can be interested in our article How to connect a 220 engine.
We connect 380 V to 220 V
The connection of a 380 V electric motor to 220 V is as follows: take a capacitor and then close the stator windings using the “Triangle” circuit or"Star-Triangle" (on the attached scheme, pay attention to the notes). Then we connect the "Phase" to the output of any of the 3 windings,and then we connect the “Zero” to the output of the other winding and connect the 2nd end of the capacitor circuit to any of the windings (the choice of windings and the sequence do not matter).
The last step should be done carefully, and do not forget to install a button to break the circuit with the starting capacitor when the acceleration of the electric motor ends. Otherwise, your equipment may fail due to overheating. And pay attention to the fact that connecting such an electric motor to a 220 V network will decrease its power.
