An AC asynchronous motor is an electric drive device that converts electrical energy into mechanical energy. It is mainly composed of stator, rotor and the air gap between them. After the stator winding is connected to the three-phase AC power supply, a rotating magnetic field is generated and the rotor is cut to obtain torque. Three-phase AC asynchronous motors have the advantages of simple structure, reliable operation, low price, strong overload capacity and convenient use, installation and maintenance, and are widely used in various fields.
basic structure
The three-phase asynchronous motor is mainly composed of a stator and a rotor. The stator is a stationary part, and the rotor is a rotating part. There is a certain air gap between the stator and the rotor.
The stator consists of three parts: iron core, winding and frame. The rotor is composed of an iron core and a winding, and the rotor winding has a squirrel cage type and a wire wound type. The squirrel-cage rotor is formed by inserting copper strips into the rotor core slot, and then welding both ends of all copper strips to two copper end rings; the wire-wound rotor winding is the same as the stator winding, which is composed of coils and placed in the rotor core. slot. Although the structure of squirrel-cage and wire-wound motors is different, the working principle is the same.
