摘　　要：针对目前汽车制造行业对加工精度的需求,为了抑制加工机床所采用的直线电机由于自身空间谐波的影响而产生的推力波动,提高机床加工精度,通过选取合适的结构参数,优化设计了一种空心永磁同步直线电机。通过有限元建模的方式获取优化数据,调整电机结构,实现对空间谐波的抑制,提高了机床的加工精度。Based on the demand for machining accuracy of automobile manufacturing industry and restraining the fluctuation of thrust ripple caused by the influence of the space harmonic used in PMLSM, it presents the method to improve the machining accuracy of the machine tool, which selects the appropriate structure parameters and optimizes a hollow synchronous linear motor.Based on the finite element modeling method, it obtains the optimal data, adjusts the structure of the motor, inhibits the space harmonic, increases the precision of the machine tools.
