Noise and Vibration Analysis of a Flux Switching Motor (FSM) with Segmental Rotor

Abstract

Flux Switching Motor (FSM) with segmental rotor is a new class of electric motor, with both AC and DC windings on the stator. The rotor is devoid of any windings. FSM with its high torque density, compactness, less heat production and high ruggedness can prove to be an ideal motor topology to be used for the propulsion systems of electric vehicles. The objective of this study is to investigate the noise and vibration characteristics of an FSM with segmental rotor due to the electromagnetic forces acting on the motor and optimize the design to reduce noise and vibration levels.
