本文介绍了一种用于汽车应用的永磁同步电机的设计方法和机械性能，该电机采用了周向分段转子。主要目标是找到转子叠片叠片的收缩力配合的替代方案并提高材料利用率。除了机械架构，重点是磁性设计，即通过使用磁阻扭矩和最小化磁体体积来实现宽磁场削弱能力。转子结构的机械性能在几个原型上进行了验证，包括扭矩过载、高速运行和平衡测试。这项工作是蒂森克虏伯Presta凸轮轴有限公司和切姆尼茨理工大学联合研究项目的一部分。
This paper presents the design approach and mechanical behavior of a permanent magnet synchronous machine for automotive applications incorporating a rotor with circumferential segmentation. Finding an alternative to shrink force fitting of rotor lamination stacks and improving material utilization are the main objectives. In addition to the mechanical architecture, the focus is on the magnetic design, i.e. implementing wide field weakening capabilities by using reluctance torque and minimizing magnet volume. The mechanical performance of the rotor structure was verified on several prototypes concerning torque overloading, high speed operation and balancing tests. This work is part of a joint research project of Thyssenkrupp Presta Camshafts GmbH and Chemnitz University of Technology.
