"WebFeb 26, 2024 · In fact, in terms of torque, it is advantageous to design the magnetic gear as an SPM type. This is because, in the case of the general IPM type, as shown in Figure 9, there is an additional piece on the inner rotor, which distorts the pole-piece permeance component. In addition, in contrast to PMSM, since it has a double-air-gap structure, the ... " - Development of spoke-type ipm magnetic gear
