摘要
内置式高速永磁电机转子在高速运行时,因受到巨大离心力的作用,极易受到损坏。针对该问题借助有限元软件对“一”字型径向充磁内置式永磁电机转子进行了强度仿真分析。提出了一种永磁体“一”字型分段内置式转子结构,通过计算不同加强筋数量时转子所受的最大应力,总结出加强筋数量对转子机械性能的影响规律,通过结果对比得出永磁体周向分段结构能有效减小转子所受应力的最大值,对高速内置式永磁转子设计具有一定的指导意义。
The rotor of the interior permanent magnet synchronous motor(IPMSM)is easily damaged due to the huge centrifugal force during high-speed operation.In order to solve this problem,the strength analysis of the rotor of the IPMSM with radial magnetization is carried out by the finite element analysis.In this paper,a"-"shaped segmented interior permanent magnet rotor structure is proposed.By calculating the maximum stress of the rotor with different number of stiffeners,the influence of the number of stiffeners on the mechanical properties of the rotor is summarized.Through the comparison of the results,it is concluded that the circumferential segmented structure of permanent magnet can effectively reduce the maximum stress on the rotor,which has a certain value for the design of high-speed built-in permanent magnet rotor guiding significance.
