| 摘 要： | 高速大功率车用永磁同步电机的转子轴系是一个涉及电磁、机械高度耦合的非线性系统，因此转子动力学性能是高速车用永磁同步电机设计必须关注的问题.建立了电机中由于转子偏心引起的电磁激励解析模型，以转子动力学和非线性动力学为基础，建立永磁电动机转子系统的非线性模型，用解析法计算得到转子横向振动的幅频特性，结果表明转子横向振动具有负刚度和失稳幅值跳跃现象.最后通过数值计算对等效解析计算的结果进行了验证.

| Abstract: | The rotor shafting of high speed and high power permanent magnet synchronous motor (PMSM) is a nonlinear system involving electromagnetic and mechanical coupling, so the dynamic performance of the rotor is a problem that must be paid attention to in the PMSM design for high speed vehicles. A nonlinear model of the rotor system was established based on nonlinear rotor dynamics. The amplitude frequency characteristics of the lateral vibration of the rotor were calculated with the analytical method. The results show that the lateral vibration of the rotor reveals negative stiffness and instability amplitude jumping phenomenon. Finally, the results of equivalent analytical calculation were verified by numerical calculation. |
