Abstract :
In this paper, it is shown that under certain conditions aerodynamic sources dominate the acoustic noise emission of switched reluctance drives. It is indicated how the noise sources can be easily identified experimentally. Additionally, simple measures to reduce aerodynamic noise are presented
