Three-phase motor basic knowledge
Apr 14, 2018

Three-phase motor means that when the motor's three-phase stator winding (the phase difference of 120 degrees electrical angle), after the introduction of three-phase AC, will generate a rotating magnetic field, the rotating magnetic field cuts the rotor windings, thereby generating induced current in the rotor winding ( The rotor winding is a closed path. The current-carrying rotor conductor will generate electromagnetic force under the action of the rotating magnetic field of the stator, thus forming electromagnetic torque on the rotating shaft of the motor to drive the rotation of the motor, and the direction of rotation of the motor is the same as that of the rotating magnetic field.
