Starting 220V AC single-phase motor is roughly divided into the following types:
The first, starting from auxiliary winding type, to start, its starting torque is not. The operating rate remains approximately constant. Mainly used in electric fan, air conditioning fan motor, washing machine motor etc..
Second, motor static centrifugal switch is connected to the power, to start after starting work in the capacitor, when the rotor speed reaches the rated value of 70% to 80% when the centrifugal switch will automatically jump, starting capacitor to complete the task, and disconnected. The starting winding is not involved in the operation, and to run the motor winding coil to action.
Third, participate in the operation of capacitor connected in series to a starting winding and running.
