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.

带孔开关磁阻电机的降噪
开关磁阻电机具有双凸极结构,定子和转子均具有凸极,结构简单,坚固耐用,在恶劣环境中具有优势。然而,它的缺点是由于径向力的变形导致电机噪声大。本文采用二维有限元法研究了各种杆内带孔srm的径向力,并对典型模型进行了噪声和效率评价。结果表明,由于径向力的减小,带孔的极点可以有效地改善噪声。
