本文讨论了一种普通显著内永磁（PM）电机的设计，也称为磁强永磁电机。采用多势垒转子的几何形状，通过解析模型对其进行研究，得到了近似正弦的气隙磁通密度波形，从而提高了性能，减小了转矩脉动。所建立的分析模型具有通用性，适用于任意数量的转子磁通屏障和任意数量的磁极。通过有限元分析对改进后的电机性能进行了评价。在电机样机上进行了实验验证。
This article deals with the design of a normal saliency interior permanent magnet (PM) motor, also referred as flux-intensifying PM motor. A multibarrier rotor geometry is adopted and studied through an analytical model to obtain an almost sinusoidal airgap flux density waveform, so as to improve the performance and reduce the torque ripple. The developed analytical model is generic and applicable for any number of rotor flux barriers and for any number of poles. The motor performance improvement has been evaluated by finite-element analysis. Experimental validation has been carried out on a motor prototype.
