Abstract

Cogging torque is a crucial and offending problem for electric machines that consist permanent magnets. Flux switching permanent magnet (FSPM) machines have magnets embedded inside the stator coils. Due to the interaction between the stator magnetic flux and the rotor steel, cogging torque occurs. To express this interaction, Magnetic Permeance Distribution Model is implemented in this study. To minimize the cogging torque, unequal rotor slot arc (URSA) technique is developed and cogging torque is calculated by using finite element method. An optimization study is performed to get the minimum value of the cogging torque under reasonable output torque. Results prove that, the proposed URSA method have promising outcomes for cogging torque reduction.

利用不等转子槽弧法降低 FSPM 电机的齿槽转矩

齿槽转矩是由永磁体组成的电机的一个关键和棘手问题。磁通开关永磁（FSPM）机器的定子线圈中嵌入了磁铁。由于定子磁通和转子钢之间的相互作用，会产生齿槽转矩。为了表达这种相互作用，本研究采用了磁导分布模型。为尽量减小齿槽转矩，开发了不等转子槽弧 (URSA) 技术，并使用有限元法计算齿槽转矩。为了在合理的输出转矩下获得最小的齿槽转矩值，进行了优化研究。结果证明，所提出的 URSA 方法在降低齿槽转矩方面具有良好的效果。
