摘 要：永磁直线同步电机正在越来越广泛应用在高精度数控机床上。推力波动是影响机床系统运动精度和定位精度的主要因素。因此减小推力波动是永磁直线同步电机优化设计的重要任务。以一台有铁心PMLSM为例，首先对端部效应力，齿槽效应力分别加以分析，通过优化初级长度，优化两个端部齿的形状，优化绕组形式，优化次级磁钢偏斜角度，并用Ansoft进行仿真，比较切向力和法向力的波动变化，最终以优化后的参数制作了验证样机。

Abstract: PMLSM are becoming more widely used in high-precision CNC machine tools. Thrust fluctuations is the main factors that affect the machine system accuracy and precision. Therefore, reducing the thrust fluctuation is important task of optimized PMLSM. First,there are core to a PMLSM,for example, the end effect force and cogging force were to be analyzed. by optimizing the core length, optimizing the shape of two ends teeth, optimizing the winding form, optimizing magnet skew angle, using Ansoft simulation to compare the tangential force and normal force changes in the volatility, and ultimately to the optimized parameters, and produced a prototype verification.
Key words: CNC machine tools, PMLSM, thrust fluctuations |
