摘要

针对扁平结构、分块式永磁体的高速永磁同步电机的碳纤维护套设计问题,给出了通用的护套参数化设计模型,能够实现护套的快速设计,并分析了护套与永磁体间的过盈量、永磁体的径向压应力、转子外径对护套设计的影响。采用三维有限元方法对转子强度的解析模型进行了验证,并结合转子温度场分析结果,针对不同温度条件下,磁极间隔导致护套弯曲应力的产生,从而威胁护套安全的问题进行了研究。对比研究了不同磁极间隔材料对护套强度的影响,得到钛合金做磁极间隔时能够有效降低护套的弯曲应力,提高护套强度。最后制作了样机,并进行了实验。

Abstract：

For the design of carbon fiber sleeve of the high-speed permanent magnet synchronous motor with segmented permanent magnets and flat structure, parametric model was proposed to achieve the rapid design of the sleeve. Influences of interference value between sleeve and magnets, radial compressive stress of magnets, and diameter of rotor on the design of sleeve were analyzed. A 3-D finite element model was built to verify the analytical results. In addition, with the temperature rise results of the rotor, it was used to investigate the problem of bending stress of the sleeve caused by pole spacers under different temperature which may result in destruction of the sleeve. The influences of different pole spacer materials on the bending stress of the sleeve were compared. As a result, the bending stress of the sleeve could be greatly decreased by titanium alloy pole spacers and the strength was optimized. A prototype was manufactured and the test was provided.

Key words： High-speed permanent magnet synchronous motor rotor strength pole spacer carbon fiber sleeve bending stress
