With the development of modern permanent magnet ( pm ) machine to high speed, high efficiency, high power density and micromation, the limitation of traditional rare earth pm machine is exhibited, such as higher ripple - free torque, higher losses, lower open - circuit magnetic field, etc. halbach motor, a new type permanent magnet motor, first proposed by american scholar klause halbach, has been studied very widely. halbach motor has higher magnetic field, usually as 1. 4 times as that of traditional rare earth permanent magnet machine, which attributes to higher power density
Halbach永磁電機是由美國學者klausehalbach提出后一直被廣泛研究的一種新型永磁電機，和普通永磁電機相比其優越性有：氣隙磁密比一般永磁電機可增大40 ，從而可有效提高電機的功率密度；固有的正弦分佈磁場，可為電機設計和加工帶來便利，降低成本；自屏蔽效應，轉子可不再需要為磁路提供閉合迴路，這為轉子的選材提供了較大的空間。
