Abstract
By reason of variation magnetic field, cogging torque is generated. Cogging torque of Spoke type motor is bigger than other type permanent magnet motor. So, this paper presents a design notch on stator and variation rotor shape to reduce cogging torque of Spoke Type motor. Through Fourier formulation of magnetic field on air gap, we found position of notch. The validity of the proposed design is confirmed with FEM analysis method.
