摘　　要：为满足超精加工等领域对高精度驱动控制系统的需要,交流永磁力矩电机正逐渐向大力矩、低脉动方向发展,但国内相关领域的研究相比于国外仍有很大的差距。根据实际需要,分析研究了大力矩、低脉动交流永磁力矩电机的结构,并根据技术要求对电机加以设计。最后利用有限元分析方法对提出的交流永磁力矩电动机进行分析,用以验证所设计的电机在过载能力、定位力矩及波动力矩的抑制等方面的性能。仿真分析结果显示所设计的电机具有优良性能。In order to meet the needs of high precision drive control system in the field of ultra-precision machining,AC permanent magnet torque motor is developing towards high torque and low ripple,and there is still a big gap between domestic and foreign research. Therefore,according to the actual engineering needs,the structure of large torque,low pulsating AC permanent magnet torque motor was analyzed,and the motor based on the technical requirements was optimized. Finally,the method of finite element analysis was used to analyze the proposed AC permanent magnet torque motor,and verified the design of the motor overload capacity,the performance of cogging torque and the suppression of the ripple torque. The simulation results showed that the designed motor had excellent performance.
