摘要

摘要针对双边永磁同步直线电机(DSPMSLM)的推力波动问题,利用ANSYS软件设计了双边永磁同步直线电机(DSPMSLM)的Halbach永磁阵列结构。在此基础上,通过改变电枢铁心端齿高度、齿槽结构和主轭副齿槽的开度等方法抑制了电机的推力波动。首先,分析了这些地区推力波动的原因。其次,通过MAXWELL仿真验证了选择合适的端齿高度可以抑制端齿力,在主轭架中使用合适尺寸的半开槽和辅助槽可以有效减小端齿力。三种方法均可抑制电机推力波动,使DSPMLSM的推力波动从11.4%降至3.28%,提高了平均输出推力,为进一步优化直线电机的输出性能提供了参考。

Analysis and Suppression of Thrust Fluctuations in Halbach-type Permanent Magnet Synchronous Linear Motors
Abstract To address the thrust fluctuation problem of a bilateral type permanent magnet synchronous linear motor (DSPMSLM) with a Halbach permanent magnet array, a DSPMLSM with Halbach permanent magnet array structure is designed using ANSYS software. And based on this motor, the thrust fluctuations of the DSPMLSM are suppressed by using methods such as changing the end tooth height of the armature core, the tooth slot structure, and the opening of an auxiliary slot in the primary yoke. Firstly, the causes of thrust fluctuations in these areas were analyzed. Secondly, MAXWELL simulations were used to demonstrate that the selection of a suitable end tooth height could suppress end forces and that the use of a suitable-sized half-open slot and an auxiliary slot in the primary yoke could effectively reduce slot forces. All three methods can be used to suppress motor thrust fluctuations, reducing the thrust fluctuations of the DSPMLSM from 11.4% to 3.28% and increasing the average output thrust, which provides a reference for further optimization of the output performance of the linear motor.
