Acoustic Noise Performance of Vector Controlled Switched Reluctance Motor with Radial Force Ripple Suppression

High acoustic noise has always been one of the main challenges in the field of switched reluctance motors (SRM), as it is caused by mechanical vibrations. To cope with this problem, reducing the torque ripple and radial force ripple of switched reluctance motors has been identified as a potential noise reduction strategy. In this research, using a current controller to drive a switched reluctance motor in a vector control manner. Specifically, by means of vector control, the constant and varied components of the torque can be decomposed into two independent parts, allowing to control the average torque and ripple separately. In this paper, it is found that such a decoupling strategy allows us to reduce not only the torque pulsation but also radial force ripple in a targeted manner, thereby effectively reducing the overall noise level.
