1. Three phrase AC induction motor

Three-phase AC induction motor is a kind of electric drive that converts electric energy into mechanical energy. It is mainly composed of the stator, the rotor and the air gap between them. After the stator windings lead to the three-phase AC power, a rotating magnetic field is generated and the rotor is cut to obtain the torque. Three-phase AC asynchronous motor has the advantages of simple structure, reliable operation, low price, strong overload capacity and advantages of using, installing and maintaining, and is widely used in various fields.

2. Features of three phrase AC induction motor

Three-phase asynchronous motor has a great feature, that is, within a certain range, can automatically adjust the relationship between load torque (torque) and speed within the maximum torque of the motor, the torque decreases with the speed increases, Motor load increases, the speed will inevitably decline, but the rotating magnetic field cutting conductor speed increases, the rotor conductor in the induction of a larger current, increasing the electromagnetic force on the rotor to promote the motor to produce greater torque.
