Development of spoke-type ipm magnetic gear
WebAug 13, 2024 · In , the main PMs can be moved to a new position under the centrifugal force, and the low air-gap flux is produced due to the effect of the non-magnetic conductor. Moreover, a spoke-type IPM machine with radially displaceable mobile yokes is proposed in [17-19]. At high speed, the increase of PM leakage flux leads to a reduction of the air-gap ...

First, the position of the magnetic bridges is changed from the air gap side to the back yoke side to increase the effective magnetic flux. Second, amorphous alloy is used for the rotor core and pole pieces in order to reduce iron loss.
WebWing-type and wing-shaped spoke-type configurations were proposed to place more and more PM poles in the rotor [83, 84]. Compared to spoke-type only structure, the airgap flux density could be enhanced by 25%, as depicted in Fig. 10 (b) and (c). Slightly higher torque output was also achieved compared to the initial rare-earth IPM machine.
