Summary:  Flux-modulated-type magnetic gears have attractive features, such as torque transmission without mechanical contact and a high torque density. However, most studies focus on steady-state characteristics, while the frequency characteristics of torque transmission remain unclear. This paper discusses a frequency response analysis for magnetic gears. The results reveal that the frequency characteristics exhibit a resonance frequency, and that torque ripple is not transmitted to the output rotor in high-frequency regions. Moreover, this paper presents a formulation of the frequency characteristics of magnetic gears by linearizing the relationship between the load angle and the transmitted torque. The linearized frequency characteristics mostly correspond with the results from nonlinear differential equations.
