LOW-SPEED OPERATION CONTROL METHOD FOR SWITCHED RELUCTANCE MOTOR, AND SWITCHED RELUCTANCE MOTOR

WIPO Patent Application WO/2022/267378

A1

The present invention relates to a low-speed operation control method for a switched reluctance motor, and a switched reluctance motor. The method comprises: acquiring a real-time rotational speed of a switched reluctance motor; determining a reference current according to the real-time rotational speed and a set rotational speed; obtaining a control parameter of low-speed operation of the switched reluctance motor according to the reference current; and according to the control parameter, controlling the switched reluctance motor to operate. According to the present invention, the reference current is determined on the basis of the real-time rotational speed and the set rotational speed of the switched reluctance motor, and the control parameter of the low-speed operation of the switched reluctance motor is obtained according to the reference current, so that low-speed operation control is performed on the switched reluctance motor according to the obtained control parameter, so as to control the switched reluctance motor to operate stably in a low-speed state, thereby improving the stability and reliability of the switched reluctance motor.
