Abstract: An SR drive with an acoustic noise reduction system for reducing vibration and acoustic noise in a switched reluctance motor (SRM). The vibration and acoustic noise at specific harmonics of current excitation in SRM are in a proportional relationship with the radial force harmonics acting at SRM stator teeth. The acoustic noise reduction system includes a processor on which is installed an acoustic noise reduction application designed to derive an optimum current waveform for generating an average torque satisfying an optimum torque condition and creating radial force with minimum amplitude at the desired order of harmonics of current excitation. A reduction in the amplitude of the specific radial force harmonics utilizing the optimum current waveform minimizes the vibration and acoustic noise in the SRM. The acoustic noise reduction system applies turn-on and turn-off angles at the optimum current waveform to improve the system efficiency.
