摘要为降低电机转矩脉动,首先提出一种五相40槽8极的非对称V型内置式永磁同步电机。在此基础上,为准确获取电机的最优参数值,提升电机转矩性能,以降低转矩脉动和提高输出转矩为优化目标,提出一种基于参数分层设计与响应曲面法相结合的多目标优化方法。通过分析优化前后非对称电机的电磁性能可知,采用改进后的非对称转子结构能有效降低电机转矩脉动。与非对称、偏移极转子结构样机相比,所提出的基于多目标优化方法设计的非对称V型内置式永磁同步电机能够在降低转矩脉动的同时提高转矩密度。

Abstract：In order to reduce the torque ripple of the interior permanent magnet synchronous motor (IPMSM), this paper proposes a five-phase, 40-slots and 8-poles asymmetric V-shape IPMSM. Taking low torque ripple and high torque output as the optimization goals, a multi-objective optimization method based on the combination of design parameter stratification and response surface method is introduced, which aims to accurately obtain the motor design parameters and improve the performance of the proposed asymmetric V-shape IPMSM. By analyzing the electromagnetic performances between initial and optimal motors, it is found that the torque ripple can be effectively reduced. Compared with the prototype of asymmetric and shifted rotor poles, asymmetric V-shape IPMSM based on the design of multi-objective optimization method can accommodate high torque density and low torque ripple.

Key words： Asymmetric V-shaped interior permanent magnet synchronous motor multi-objective optimization design parameter stratification response surface method
