摘　　要：对混合动力电动代步车用电机的要求是高效、高功率密度和低脉动转矩。Halbach电机是一种新型永磁电机,独特的永磁体结构不仅使其磁极磁场呈正弦分布,而且还可以增加气隙磁通密度,削弱转子轭部磁通密度,在提高电机功率密度的同时,减小了体积并提高了效率。用场路结合的方法设计和试制的样机均达到了混合动力电动代步车的控制要求,应用价值高。The requirements of the motor used in the hybrid electric scooters were of high-efficiency,high-power density and low pulsating torque.It was a new type of synchronous motor with the unique structure of permanent magnet to form a sinusoidal field distribution which made it not only to increase the air-gap flux while decreasing the rotor yoke flux but also to improve the power density and efficiency while reducing the motor cubage.The prototype designed by the method combined the field and circuit,met with the requirements of the motor used in the hybrid electric scooters,showing very high applicable value.
