Abstract

The present invention discloses a torque control method and device of a reluctance motor, a storage medium and a reluctance motor. The method comprises the steps of: determining the current compensation amount of the reluctance motor; and adding the current compensation amount to a given voltage of a motor controller of the reluctance motor to achieve the compensation of the torque pulsation for the reluctance motor caused by the counter electromotive force harmonic wave. According to the scheme, the problems are solved that the torque pulsation and the noise of the motor are large when the reluctance motor is operated, and the effect on reduction of the torque pulsation and the noise of the motor is achieved.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a torque control method, device, storage medium and reluctance motor of a reluctance motor, in particular to a method, device, storage medium and reluctance motor for suppressing torque ripple of a reluctance motor. motor. Background technique [0002] The reluctance motor is a low-cost, high-performance AC synchronous motor. Its wide field-weakening speed range, good inverter utilization and high efficiency make the reluctance motor applicable to electric vehicles. [0003] However, the back electromotive force of the reluctance motor is a non-standard sine wave, which contains harmonic components, which will increase the harmonic components of the flux linkage in the stator winding, which will not only increase the loss of the reluctance motor, but also increase the vibration and noise of the motor. Especially when entering the high-speed operation of field weakenin...
