摘要:
 针对碳纤维固定的高速分块表贴式永磁同步电机( SPMSM) 的转子强度缺乏解析解的问题,基于平面应力模型,采用极坐标下的位移法和应力函数法,推导了考虑永磁体和极间填充块密度及热膨胀系数差异影响的转子强度解析解,并通过有限元法对解析解的准确性进行了验证。在转子强度解析解的基础上,进一步研究了转速、碳纤维护套厚度及碳纤维护套与永磁体间的过盈量等参数对转子强度的影响。结果表明: 解析解和有限元法的计算结果相吻合,解析解能够计算考虑永磁体和填充块密度及热膨胀系数差异影响的碳纤维固定高速分块表贴式永磁同步电机的转子应力分布。
Abstract:
 Aiming at the lack of analytical solution of rotor strength for high speed segmented surface mounted permanent magnet synchronous machine ( SPMSM) with a carbon fiber sleeve,the analytical solution of rotor strength is proposed based on the plane stress model. The displacement method and stress potential method in polar coordinates were employed to deduce the analytical solution,and the influences of different densities and coefficients of thermal expansion of permanent magnets and pole fillers were
taken into account. Then the effectiveness of the analytical solution was validated by finite element method.The effects of design parameters on rotor strength,such as rotational speed,thickness of carbon fiber sleeve and interference fit between the carbon fiber sleeve and the permanent magnet,were further investigated based on the analytical solution proposed. It is shown that the results calculated by the analytical solution and finite element method are in good agreement with each other. The analytical solution proposed can predict the stress distribution of the high speed segmented SPMSM’s rotor with a carbon fiber sleeve,considering the effects of difference in density and coefficient of thermal expansion between permanent magnets and pole fillers.
