摘要

Models based on Schwarz–Christoffel's transformation of a salient PMSM with rotor eccentricity is presented. At first, motor's direct-quadrature (d-q) axis's armature-reaction field under square wave magnetomotive force is calculated. Then, d-q armature-reaction field under magnetomotive force without regular distribution is analyzed. Finally, armature-reaction field can be obtained by superposing them. This method can be applied to magnet calculation of different types of motors with rotor eccentricity. Armature-reaction field of this motor was calculated by using this analytical method and Finite Element Method (FEM). The results shows that the two cases agree well, and the validity and accuracy of the presented method are verified.%本文基于许-克变换针对转子偏心凸极永磁电机建立了磁场计算模型.首先计算方波磁势作用下电机的直、交轴电枢磁场;然后计算不规则磁势分布条件下的直、交轴电枢磁场;电枢磁场即为两者叠加.该方法适用于各种偏心情况下的电机磁场计算.将本模型计算的电枢磁场分布与有限元比较,结果吻合,证明其准确性和有效性.
