Abstract

A switched reluctance motor has a doubly salient structure, both stator and rotor have the saliency and it has an advantage in a harsh environments due to a simple and robust structure. However, it has the disadvantage that the motor is noisy because of the deformation by the radial force. This paper examines the radial force for various SRMs with a hole inside the pole using the two dimensional finite element method, and for typical models, the acoustic noise and efficiency are evaluated by the experiments. It is cleared that poles with a hole are effective to improve the noise, because the radial force reduces
