摘要

Cogging torque and permanent magnet electric machines are difficult to separate. This torque always remains overdue to the interaction between the magnetic field caused by the permanent magnet against the stator slot. The method proposed for reducing cogging torque in this study is the Half cylinder anti-notch design and sequence with the cutting-edge design. It further considers the implement of changes the slot width of the stator and the change of distance between the permanent magnets. The models reproduced employing 2-D FEMM 4.2 version. It is noticed that the cogging torque will be considerably cut down if the width of the slot opening of the stator is equal to the anti-notch width. Decreasing the distance between the permanent magnets can further cut down the cogging torque and the cogging torque ripple is flatter than the reference model. Both models will reduce the surface space of the air gap. Moreover, the proposed models can be employed to reduce the cogging torque, causes the rotation of the rotor more effortlessly and can lessen the friction on PMSG.
