摘　　要：该文利用Ansys分析计算了横向磁通电机定子在不同结构下,电机的空载漏磁系数。找出了使电机漏磁系数最小和制造工艺最简单的定子结构,并作了进一步的分析和比较。定子极靴的底边与转子弧为同心圆时,电机的漏磁系数最小。底边为直边时,漏磁系数最大。底边为正梯形时,由于其形状接近于同心圆,因此漏磁系数较倒梯形要小。而在制造工艺上,直边形最简单。因此在设计电机时需将制造工艺与漏磁系数进行综合考虑,选择最优的方案。此外,该文对定子槽部的一种结构也作了优化,使电机能够获得较大的气隙磁密。Analyzed the leakage flux coefficients of a transverse flux motor with no load under different stator structures using Ansys in this article.Stator structures with least leakage flux coefficient or with easy making techniques were out and compared further.When a concentric circle of the pole-stator hemline is the same with rotor arc,the motor magnetic flux leakage coefficients are the minimum.When the Pole-stator hemline is a straight edge,the leakage magnetic coefficients are the maximum.When the hemline is a echelon,the leakage magnetic coefficients are more minimum compared with the ones of inverse echelon for its shape is similar to the concentric circle,while in manufacturing process,the straight edge is the simplest one.Therefore give a comprehensive consideration of the manufacturing process and leakage magnetic coefficients while in the design of the motor manufacturing technology,and thereby select the optimal solutions.Besides one of the slot structures of the stator was also optimized in this article in order to get larger airgap flux density.
