摘　　要：针对五相实心转子感应电机磁场分布复杂,转子侧阻抗参数受磁通密度和转差率影响难以准确计算,而子域法计算复杂,不满足电机设计初期快速计算的要求等问题,将电机求解域划分为定子槽载流子域、槽开口子域、气隙子域和实心转子子域,结合安培环路定理和静磁学原理对定子槽边界条件进行简化.采用傅里叶级数法对气隙和实心转子交界面条件进行分析,建立用于磁场计算的快速子域模型,求得各子域磁场分布.在此基础上计算转子阻抗和电磁转矩,随后搭建有限元模型并与解析结果进行对比,验证了快速子域模型的正确性.The magnetic field distribution of the five phase solid rotor induction motor is complicated,and the rotor side impedance parameter is affected by the flux density and slew rate.The subdomain method is complicated,which does not meet the requirements of rapid calculation at the early stage of motor design.In this paper,the motor solution domain was divided into stator slot current-carrying subdomain,slot opening subdomain,air gap subdomain and solid rotor subdomain,and the stator slot boundary conditions were simplified by combining the Ampere loop theorem and static magnetism,then the Fourier series method was used to analyze the air gap and solid rotor interface conditions.A rapid subdomain model for magnetic field calculation was established and the distribution of the magnetic field in each subdomain could be obtained.Then,the rotor impedance and electromagnetic torque were calculated based on the model.Finally,a finite element model was established to compare with the analytical results,which verified the correctness of the fast subdomain model.
