The working principle of the three-phase asynchronous motor animation demo

Three-phase asynchronous motor is a kind of commonly used industrial drive motor, the rotor speed is lower than the speed of the rotating magnetic field, rotor winding due to there is relative motion between magnetic field and induced electromotive force and the current, electromagnetic torque and interact with the magnetic field, the 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 kinds. 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 rotor and stator is also set up a three-phase winding and through the slip ring, brush with external resistor connection. The following through the flash animation, please watch the working principle of three phase asynchronous motor.
