摘要
该文提出了一种新型12/8极电励磁双凸极轮毂电机的结构。采用有限元方法对电机内的磁场进行计算,得出了电机空载时的磁场分布,并研究了不同励磁电流下电机的气隙磁密特性、磁链特性以及反电势波形,所得结果为电机负载时选择励磁电流和换相角度提供了依据。
It proposed a novel structural 12/8 poles doubly salient electro-magnetic wheel-hub motor.Caculate the magnetic field inside the motor with finit element method to acquire the electric field distribution.The no-load gap-flux density,flux characteristic and EMF diagram of the motor under different excitation currents was researched.The result supplies references for selection of excitation current and commutation method when loading.
