Abstract
A switched reluctance motor speed regulator is composed of a switched reluctance motor, a power driver, an operation unit, and a control unit. The switched reluctance motor is internally equipped with a temperature sensor which thermally protects the motor. The turn-on and shut-down of a switch device in the power driver can enable current of a stator winding of the reluctance motor to be switched on or off and drive a rotor to output rotation at a certain torque. The operation unit is an interface circuit of the control unit and external operation. The control unit comprises a hardware part and a software part. By detecting work current of a phase winding of a power main circuit and calculating the actual position and real-time rotation speed of the rotor of the reluctance motor based on the actual curve characteristic of the motor, the control unit controls the turn-on and shut-down of the switch device of the power driver. The witched reluctance motor speed regulator is advantaged by simple structure, high reliability, high efficiency, and obvious energy-saving effect.
