In order to improve the transmission torque of magnetic gears, the planetary transmission was applied to the design of ~tic gear drive. The 2K-H type permanent magnetic planetary gear drive was presented, and the analytical expressions of torque for this drive was deduced with equivalent current model method. Through analyzing the effects of design parameters on torque, the system design parameters were determined, the experimental prototype and experiment of the permanent nuzgnetic planetary gear drive were designed. Transmission ratio, the maximum torque and transmission efficiency were measured. The experimental results showed that the prototype ran normally and smoothly, and the transmission effwiency was high. So the torque expression was correct, the selection of parameters and the prototype structure design were reasonable.
