【摘要】 永磁电机转子强度计算的难点在于电磁场产生的电磁力与边界接触力的耦合作用的计算。本文应用有限元分析软件Ansys,通过二维电磁-结构耦合场对永磁电机转子强度进行求解,获得了在计及电磁耦合作用条件下的永磁电动机转子强度计算结果,并得出了电机转子的应力分布情况,为此类电机设计提供了参考。更多还原

【Abstract】 The important aspect in the calculation of intensity in a rotor is the coupled interaction between the electromagnetic field and the deformation/force on the contact boundaries.Based on the FEM software Ansys,the rotor’s intensity and radial shift are acquired by two-dimensional coupled-filed FEM,with the consideration about coupled electromagnetic-mechanical problems.更多还原
