In order to solve the problem of small transmission power and large space occupation of the magnetic vortex coupler, a hybrid magnetic coupler is proposed. A 3D magnetic field finite element distribution model was built according to the effects of the structural parameters of this hybrid magnetic coupler on its dynamic performance, its structural parameters were optimized by an improved response surface methodology (IRSM), and then the correctness of these optimized parameters was verified in a self-designed test. The structural parameters of this hybrid magnetic coupler were optimized using IRSM, the optimization results showing that the magnetic flux density in this hybrid magnetic coupler increased by 5.01 times. According to the test results, the maximum error between the test value and the optimal value of maximum torque, average output speed and slip is 11.9 %, 5.3 % and 9.7 %, respectively, suggesting that this optimization method is tenable. The results could serve as theoretical and technical bases for the design of hybrid magnetic couplers.
