摘　　要：基于麦克斯韦电磁理论,建立电机有限元电磁场分析模型,得到电机磁场强度分布云图,通过分析电机齿部和轭部典型位置磁密径向、切向磁密波形,求取其磁密幅值。基于Bertotti铁耗分离理论,计算了某高速动车组牵引电机铁心损耗,同时分析了电机的铜耗和机械损耗。Based on Maxwell′s electromagnetic theory,the finite element electromagnetic field analysis model of the motor is established,and the magnetic field intensity distribution cloud diagram of the motor is obtained.By analyzing the radial and tangential magnetic density waveforms of the typical positions of the tooth and yoke of the motor,the magnetic density amplitude is obtained.Based on Bertotti′s iron loss separation theory,the core loss of the traction motor of a high-speed EMU is calculated,and the copper loss and mechanical loss of the motor are analyzed.
