| 摘 要： | 高速永磁电机的永磁体抗拉强度很小,不能承受转子高速旋转产生的离心力,因此需要一个过盈配合的高强度防护套对永磁体进行保护。主要分析了转子护套和永磁体间过盈配合量及应力的计算方法,对一台额定转速60 000 r/mim的高速永磁电机,计算了过盈量的值以及护套和永磁体的应力,并根据计算的过盈量采用ANSYS Workbench12.1分析了护套和永磁体的应力。结果表明,理论计算值与ANSYS的仿真结果接近,能够满足高速下保护永磁体的要求。

| Abstract: | The permanent magnet(PM) material used in high-speed PM electric machine has very small tensile stress,and it can't withstand the huge centrifugal force due to high speed.So,a high-strength sleeve with interference fit is necessary to protect the permanent magnet.This paper mainly analyses the calculation method of interference fit and stress between the PM and sleeve.For a high-speed PM electric machine rating 60000rpm,the interference fit and stress is calculated firstly,then the theoretical calculation r... |
