Single-phase asynchronous motor is composed of stator, rotor, bearing, housing, end cover, etc.

The stator consists of a frame and a core with windings. The core is made of silicon steel notching veiw and trough embedded with two sets of space across 90 ° electrical Angle of each main winding (also known as running winding) and the auxiliary winding up deputy winding (also known as starting around). The main winding is connected to ac power supply, and the secondary winding is connected to centrifugal switch S or start capacitance, running capacitance, etc., and then connected to power supply.

The rotor is a cage cast aluminum rotor, which is formed by casting aluminum into the groove of the core after the core is superimposed, and the end ring is cast together to make the rotor guide bar short circuit into the cage.

Single-phase induction motor is divided into single-phase resistance starting induction motor, single-phase capacitor starting induction motor, single-phase capacitor running induction motor and single-phase double-value capacitor induction motor.
