Abstract The transient characteristics of a dual-flux-modulator coaxial magnetic gear (DFM-CMG) under different conditions such as start-up and the abrupt load changes were first investigated. Based on an electromagnetic finite-element (FE) model of the DFM-CMG, the torsion and transient models considering the nonlinear relationship between magnetic torque and relative position of the two rotors were developed. The torsion properties of a DFM-CMG prototype were tested to validate the accuracy of simulation results. Moreover, the calculated and experimental results of transient characteristics show that the DFM-CMG has better load tracking capability. Then, electromagnetic force (EF) generated by the interaction between the pole-pieces of the auxiliary flux modulator and the two rotors was investigated. Finally, the EF obtained from electromagnetic FE model was loaded to the pole-pieces of the auxiliary flux modulator in multi-physics simulation model to calculate the vibration characteristics. The results of vibration simulation show that the frequencies of EF are far from the resonance frequencies of the auxiliary flux modulator and the maximum deformation of the auxiliary flux modulator is rather smaller than the allowable deformation.
