摘　　要：针对高速表贴式永磁转子的不同保护型式,建立了三层配合下的表贴式永磁转子应力解析计算模型,基于该解析计算模型对钛合金护套和碳纤维护套保护下的永磁转子进行设计,并通过有限元法对解析计算模型的正确性进行验证。研究了不同护套材料、过盈量、极间填充材料、温度等因素对护套等效应力的影响规律。建立了高速表贴式永磁转子涡流损耗与温升的计算模型,研究了不同护套保护措施、不同填充材料下,永磁转子涡流损耗分布与永磁体温升特性。在此基础上,完成了一台高速表贴式永磁电机的设计与制造,并进行了实验,结果证明了该文计算分析的正确性。For the different protection type of high-speed surface-mounted permanent magnet (SMPM) rotor, an analytical calculation model for the stress calculation of SMPM rotor was established. Based on the analytical model, PM rotor with carbon fiber (CF) and titanium alloy (TA) was designed. And the analytical calculation model for different enclosure protection methods was verified by finite element method (FEM). The effects of different enclosure materials, interference, pole filler materials, and temperature on the enclosure equivalent stress were analyzed. A calculation model of eddy current loss and temperature rise of high-speed SMPM rotor was established. Eddy current loss distribution and PM temperature rise with different enclosure protection measures and different pole filler materials were studied. On this basis, the design and manufacture of a high-speed SMPM motor was designed and tested, it provides effectiveness verification of the analytical method.
