Abstract

This paper presents a study on control strategy for active vibration cancellation and noise reduction in SR motor. It has been revealed that 2-stage commutation control based on natural frequency of stator body has been effective to suppress the vibration occurring on the stator body. According to some considerations on generation mechanism of the vibration, a new active vibration cancellation control for variable speed SR motor drive under digital PWM control is proposed. Experimental studies using 12kW three-phase 12/8 SR motor demonstrates that the proposed 2-step commutation control using negative voltage PWM is much effective as active vibration cancellation and noise reduction technique.
