Rotor Design for Reducing the Switching Magnetic Noise of AC Electrical Machine Variable-Speed Drives

Abstract

This paper is focused on the analysis of the acoustic noise of the magnetic origin emitted by ac electrical machine variable-speed drives. First, the principle of noise generation is presented as well as the method for taking into account the effects of the current harmonics on noise generated by the pulsewidth modulation supply. The experimental results… (More)
