This article presents the design studies of a multi‐layer interior permanent magnet synchronous motor (IPMSM) with a radially oriented arc‐shaped hot‐deformed magnet for automotive traction drives. Specifically, by using the IPMSM on a 2010 Prius as a benchmark, we designed an IPM rotor geometry that simultaneously achieves a 20% improvement in both the maximum power and constant output power line with high efficiency while maintaining maximum torque. A prototype of the designed three‐layer IPMSM was manufactured and evaluated. The results of the tests conducted on the prototype are reported and discussed in this article.

IPMSM的径向取向弧形热变形磁体用于汽车牵引驱动器的设计研究

本文介绍了一种多层内部永磁同步电动机（IPMSM）的设计研究，该电动机具有用于汽车牵引驱动的径向定向的弧形热变形磁体。具体来说，我们以2010年普锐斯（Prius）上的IPMSM为基准，设计了IPM转子几何结构，该几何结构可在保持最大扭矩的同时高效地将最大功率和恒定输出功率线提高20％。制造并评估了设计的三层IPMSM的原型。本文报道并讨论了在原型上进行的测试结果。
