摘要： 针对低速大转矩用盘式横向磁通电机中存在的C型定子结构不稳定，电机尺寸过大和生产效率低，U型定子和E型定子槽满率低、转矩密度小等问题，提出一种将绕组绕制在U型定子铁心两端的多层绕组盘式横向磁通电机拓扑结构。介绍了电机的结构和原理，并建立该电机基于磁阻的三维等效磁网络模型。在考虑永磁体空间漏磁的情况下，对主磁通进行计算并推导了空载磁链、空载反电动势和主要尺寸的关系。通过与双层绕组盘式横向磁通电机齿槽转矩、转矩密度和功率因数三维有限元结果的对比研究，分析所提出电机结构的优越性和有效性。试制出一台样机并进行空载反电动势的实验测试，通过仿真和实验测试的结果对比，验证该建模分析方法的准确性。性。

Abstract: Aiming at the problems of unstable structure, oversized and low productivity of C-stator, and low slot fullness and torque density of U-stator and E-stator in the disk transverse flux motor for high-torque and low -speed, a new multi-layer winding disk transverse flux motor topology with windings wound at both ends of the U-stator is proposed. The structure and principle of the motor are introduced, and a reluctance-based motor 3-D equivalent magnetic network model established. The relations between the no-load flux linkage, back-EMF and the main dimensions are calculated and derived for the main magnetic flux considering the spatial leakage of the permanent magnets. The superiority and effectiveness of the proposed motor structure is analyzed through a comparative study with the 3D finite element results of cogging torque, torque density and power factor of a double-wound disk transverse flux motor. A prototype machine is piloted and tested for the back-EMF, and the accuracy of the modeling and analysis method is verified by comparing the results of simulation and experiment.

Key words: transverse flux, disk motor, 3D equivalent magnetic networks, inter-pole flux leakage, multi-layer winding
