Composite Magnetic Couplers

This paper addresses the problems of low output torque, large footprint and low transmission efficiency of magnetic couplers by combining the structural features of disc and barrel magnetic couplers with the advantages of Halbach's permanent magnet arrangement. With the same volume and size requirements, the torque performance of this coupling is better than that of the traditional disk and barrel coupling, and it has the advantages of large stable operation range, adaptable to load disturbance and large output torque at low speed difference, which improves the transmission efficiency.
