Working principle of three-phase asynchronous motor
Main components of three-phase asynchronous motor:
It is composed of stator (fixed part) and rotor (rotating part), end cover, fan, hood, etc.
Working principle of three-phase asynchronous motor:
When the stator windings are connected with symmetrical three-phase alternating current, a rotating magnetic field is generated in space. As the rotor is cutting the magnetic force line, induced electromotive force and force are generated on the rotor at the same time. Thus, the electromagnetic torque is formed on the motor shaft, driving the motor to rotate, and the motor rotation direction is the same as the rotating magnetic field direction.
