Surface permanent magnet structure of pm machines is widely used in these types of machines. In the slotted machines, low armature reaction and high overload capability features can be achieved by selecting surface permanent magnets. A uniform air gap, the basic nature of a permanent magnet motor with surface permanent magnet and without slots. Cogging torque creates variable reluctance of the air gap because of slots existence. Cogging torque can be reduced in different ways. This paper surveyed two pm setting methods that are inclusive shifting and sliced surface pm. Results show that shifting method has more effect on reducing of cogging torque.
