磁悬浮电机转子加强环设计及工艺研究

针对某型号磁悬浮永磁电机转子磁环胶接强度不能满足工作要求的问题，提出采用M46J／L1000复合材料缠绕加强环的保护设计方案，根据工艺实验结果，利用有限元分析软件MSC．Patran／Nastran对该结构进行应力和形变分析，并确定了合适的成形工艺参数，完成了转子加强环试验件的制作。结果表明：M46J／L1000复合材料体系满足材料组分要求，缠绕复合材料加强环结构满足磁悬浮电机转子在72000r／min高速转动时强度和变形要求。

Study on Design and Process of Rotor Strengthen Ring in Magnetic Levitation Motor

To increase the joint strength of the rotor and the magnetic ring in the magnetic levitation motor, a strengthen ring is introduced by M46J/L1000 carbon fiber reinforced epoxy composite wounded on the bearing. Finite element analysis software MSC. Patran/Nastran is used to analyze the stress and deformation of the structure based on the data of process test, and appropriate process parameters are obtained. Finally, strengthen ring is com- pleted by means of filament winding. Experimental results show that M46J/L1000 composite satisfies the require- ments of the composition of material, and the composite structure of strengthen ring also satisfies the requirements of strength and deformation of the rotor in the magnetic levitation motor when it is rotating at a high speed of 72 000 r/ min.
