摘要

为提高高速磁悬浮永磁电机的综合性能，得到最优的设计参数，针对一台30 kW，48 000 rpm的磁悬浮电机进行了电磁场、转子动力学以及转子强度分析，提出一种基于多物理场分析结果的电机尺寸优化方法。使用ANSYS以及ANSOFT对电机进行建模和有限元分析，并用ISIGHT软件进行集成优化设计。以转子损耗最小为优化目标，电机几何尺寸为设计变量，在优化过程中考虑尺寸变化对电机转子模态以及强度的影响，以尺寸、电机电磁性能、力学性能等为约束条件。经过优化后，电机的转子损耗减小16.7%，其余性能均符合设计要求。根据优化设计结果加工了样机并进行电机对拖与温升实验，结果证明了优化设计的合理性，验证了本文提出方法的正确性。

Abstract

To improve the overall performance of high-speed magnetic suspension PM machine and obtain the optimal design parameters

an electromagnetic filed

rotor dynamics and rotor strength analysis was conducted on a magnetic suspension machine (30 kW

48 000 rpm)

and a size optimization method based on such multi-physics analysis was put forward. Used ANSYS and ANSOFT to carry out modeling and finite element analysis on the motor

and then completed the integrated optimization designed by adopting the ISIGHT software

taking the impact of dimensional change on the rotor model and rotor strength into consideration

with the minimum rotor loss as the optimization goal

geometric dimension of the motor as the design variable

and dimension

magnetic performance and mechanical performance as the constraint conditions. After such optimization

rotor loss of the motor was decreased by 16.7%

with other performances in compliance with the design requirements. Then a back-to-back test and temperature rise test were carried out in the model machine based on the optimization design results. The test results verify the reasonability of such optimization design and correctness of the method put forward in this paper.
