Three-phase asynchronous motor

As a motor running of three-phase asynchronous motor.Three-phase asynchronous motor rotor speed is lower than the speed of the rotating magnetic field,rotor winding due to single phase ac motor there is relative motion between magnetic field and induced electromotive force and the current,electromagnetic torque and interact with the magnetic field,the realization of energy conversion.Compared with single phase asynchronous motor,three-phase asynchronous motor operation performance is good,and all kinds of materials can be saved.According to the different rotor structure,three-phase asynchronous motor can

be divided into the cage and winding type two single phase asynchronous motorkinds.The cage rotor asynchronous motor has simple structure,reliable operation,light weight,cheap,has been widely used,its main drawback is that control difficult.Wound rotor three-phase asynchronous motor 5kw permanent magnet generator rotor and stator www.dongfeng-motor.com is also set up a three-phase winding and through the slip ring,brush with external resistor connection.Adjust the rheostat resistance can improve the starting performance of the motor and to adjust the speed of the motor.
