| 针对永磁同步伺服电机转矩脉动直接影响轻工设备伺服系统的控制精度的问题，课题组提出了一种优化电机定子齿冠的方法来抑制电机转矩脉动。基于不等气隙长度的思想，该方法的宗旨是保持定子齿冠中间部分对应的气隙长度不变，而齿冠对称轴两边的气隙变长，通过合理选择电机定子齿冠的形状能够抑制电机转矩脉动。使用有限元软件搭建12槽8极永磁同步伺服电机样机进行仿真计算，通过对定子齿进行优化，电机电磁转矩脉动和齿槽转矩得到了抑制。研究表明采用课题组提出的方法能够优化电机转矩脉动，对设计高性能电机具有参考意义。 |

| Permanent magnet synchronous servo motor torque ripple directly affect light industrial equipment control accuracy of servo system. To solve the problems, an optimization of motor stator crown to reduce PMSM torque ripple was proposed by the research group. Based on the idea of unequal air gap length, the purpose of this method was to keep the air gap length of the middle part of the stator crown unchanged, while the air gap length of the two sides becomed longer, and by reasonably choosing stator tooth crown shape could inhibit the motor torque ripple. A 12 slot 8 pole PMSM prototype was built with finite element software, by optimizing the stator teeth, electromagnetic torque ripple and cogging torque were suppressed.The method can optimize torque ripple of PMSM, and it has great significant to design high performance motor. |
