摘　　要：为了有效地提高永磁同步电机的转矩性能和降低齿槽转矩,选取48槽、8极的内置式永磁同步电机为例,在不改变转子径向半径的前提下,选取转子的关键参数作为优化参数,基于田口算法对内置式永磁同步电机进行多目标优化,在有效降低齿槽转矩的基础上增大内置式永磁同步电机的转矩性能。在优化基础上,对空载运行、额定负载、最高转速3种永磁同步电机典型的运转工况进行有限元仿真。数据结果表明:齿槽转矩峰峰值从1.8 N·m降低至0.9 N·m,额定负载下的平均电磁转矩从73.17 N·m增长至77.12 N·m,最高转速运行下的平均电磁转矩从37.3 N·m增长值38.42 N·m,分别实现了提高永磁同步电机转矩性能和降低齿槽转矩的目标。To effectively improve the torque performance of the permanent magnet synchronous motor and reduce the cogging torque,the built-in permanent magnet synchronous motor with 48 slots and 8 poles was selected as an example,and take the key parameters of the rotor as the optimization parameters without changing the radial radius of the rotor,and the multi-objective optimization of the motor was carried out based on the Taguchi algorithm,so as to increase the torque performance of the motor on the basis of effectively reducing the cogging torque.On the basis of the optimization,the three typical operating conditions of permanent magnet synchronous motors,including no-load operation,rated load and maximum speed operation,was simulated by the finite element analysis.The results show that the peak value of cogging torque decreases from 1.8 N·m to 0.9 N·m,the average electromagnetic torque under rated load increases from 73.17 N·m to 77.12 N·m,and the average electromagnetic torque increases from 37.3 N·m to 38.42 N·m at the maximum speed,respectively,achieving the goals of improving the torque performance of permanent magnet synchronous motor and reducing cogging torque.
