Abstract

This paper focuses on simulation of noise radiated by Switched Reluctance Motors for automotive powertrains. Since control for maximum efficiency leads to high torque ripple and noise radiation, optimizing the NVH behaviour is essential. The simulation approach, based on electro-magnetic and vibro-acoustic finite element models and applicable to other electric motors, is illustrated with concrete results.
