Background

The reluctance motor is an electric transmission device which can continuously run, and its structure and working principle are different from traditional AC and DC motors, it does not depend on the interaction of magnetic field produced by stator and rotor winding current to produce torque, but rather depends on "reluctance minimum principle" to produce torque, mainly the magnetic conductance of transverse axis is different from that of longitudinal axis, and it depends on the change of said magnetic conductance to produce synchronous torque (also called reluctance torque) to maintain the motor to run at a certain synchronous speed, when the reluctance motor is used, it needs to use controller to make on-off control.
