| 摘要: | 为降低直线电机的推力波动, 提出一种同极同槽双边平板型永磁直线同步电机(Permanent Magnet Linear Synchronous Motor, PMLSM), 且采用不同方法优化其结构参数. 为确定电磁设计方案, 根据同极同槽双边平板型PMLSM的结构特点和旋转电机的设计方法, 推导出适用该电机的电磁设计公式, 并建立二维有限元仿真模型进行分析和验证. 随后采用田口法筛选优化变量, 分别通过单参数扫描和基于克里金代理模型的粒子群算法进行优化. 结果表明, 在满足推力不低于600N的前提下, 推力波动大幅降低, 且永磁用量减少了13％. |
| Abstract: | To reduce the thrust ripple of linear motor, a double-sided flat permanent magnet linear synchronous motor (PMLSM) with the same number of poles and slots is proposed, and different methods are used to optimize its structural parameters. To determine the electromagnetic design scheme, an electromagnetic design formula suitable for this motor is derived based on the characteristics of the double-sided flat PMLSM and the design method of rotating motors, and a two-dimensional finite element simulation model is established for analysis and verification. Then, Taguchi method is used to screen the optimization variables, and both the single- parameter sweeping method as well as the particle swarm algorithm based on Kriging surrogate model are adopted for the optimization. The results show that under the premise of ensuring a thrust not less than 600 N, thrust ripple is significantly reduced while reducing permanent magnet usage by 13%. |
