introduction：Three-phase asynchronous motor Three-phase asynchronous motor，The speed of the rotor is lower than the speed of the rotating magnetic field，Due to the relative motion between the rotor winding and the magnetic field, electromotive force and current are generated，And interact with the magnetic field to produce electromagnetic torque，Realize energy conversion。 According to the rotor structure，It can be divided into two types: cage type and winding type。Compared with single-phase asynchronous motor，The operation performance of three-phase asynchronous motor is good，And can save a variety of materials。The structure of the cage rotor asynchronous motor is simple、Reliable operation、Light weight、cheap，But the speed is difficult.。The winding type and stator are provided with three phase winding and pass through slip rings、The brush is connected to an external rheostat。Adjusting rheostat resistance can improve motor starting performance and adjust motor speed。
