文摘
- •
A practical and efficient approach for the cogging torque reduction is proposed.
- •
The approach relies on dividing PMs radially and shifting PM pieces peripherally.
- •
The cogging torque of the AFPM machine can be reduced about 87% using this method.
- •
The negative impact of the proposed method on generator loadability is negligible.
- •
Using this approach, PM eddy losses are reduced due to the magnet segmentation.
