Structure and working principle of three-phase asynchronous motor
2026-07-14A three-phase asynchronous motor is a type of electric motor that is powered by simultaneously connecting to a three-phase AC power source (with a phase difference of 120 degrees). Due to the fact that the rotor and stator of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, hence it is called a three-phase asynchronous motor.Working principle: A three-phase asynchronous motor is an induction motor. After a current is applied to the stator, some of the magnetic flux passes through the short-circuit ring and generates induced current in it. The current in the short-circuit ring obstructs the change of magnetic flux, resulting in a phase difference between the magnetic flux generated by the short-circuit ring and the non short-circuit ring, thus forming a rotating magnetic field. After being powered on, the rotor winding induces electromotive force and current due to relative motion with the magnetic field. That is, the rotating
