Single phase motor generally refers to single-phase AC power supply (AC220V) power supply of single-phase asynchronous motors. The utility model is a device for converting electric energy into mechanical energy, and the singlephase asynchronous motor has the advantages of small capacity, single phase power supply and convenient operation, and is widely used in the fields of industry, agriculture, living appliances and the like. Typical applications such as washing machines, electric fans, refrigerators, air conditioners, pumps, blowers, juicer, soya bean milk machines, etc.
The operation for single phase electric motor:
First, the starting circuit with centrifugal switch, starting winding and capacitor not only play a role in starting, running also play a role, so that it can improve the efficiency and power factor of the motor, so the motor operation performance is better than the capacitor start motor. The capacitance of capacitor running motor starting winding series capacitor, is mainly based on the performance requirements and determine, therefore according to the performance requirements than the starting capacitance determined to be small, and the motor starting capacitor start motor performance is not as good as good. The capacitor operated motor does not start the switch, so the structure is relatively simple and the price is cheaper. It is mainly used in electric fans, air conditioners, fans, motors, washing machines and other motors.
The second type, in the starting loop of the centrifugal switch, this connection is generally used in air compressors, cutting machines, woodworking machines and other heavy load and unstable place.
