摘要

高速大功率永磁同步电机的设计受到多物理场耦合甚至冲突以及功率变换器规格的极大限制。因此，通过一步一步的计算来获得一个可行的电机设计方案是一个挑战。以350kw、13.5 krpm的非凸极永磁同步电机为研究对象，采用多物理场方法对其进行了优化。相关设计方面包括电磁方案、转子力学优化和计算流体动力学(CFD)热验证。

Multi-Physics Design of High-Speed Large-Power Permanent Magnet Synchronous Motor

Design of high-speed large-power permanent magnet synchronous motor (PMSM) is extremely constrained by the multi-physics couplings and even conflicts, and also by the specification of power converter. Therefore, it is challenging to achieve a feasible solution of motor design through the step-by-step calculation. As a study case, a 350 kW and 13.5 krpm non-salient PMSM was developed and optimized with multi-physics methods. The related design aspects include electromagnetic scheme, rotor mechanical optimization, and thermal validation with computational fluid dynamics (CFD).
