Abstract
By reason of variation magnetic field, cogging torque is generated. Cogging torque of IPM is bigger than other type permanent magnet motor. So, this paper presents a Optimizeing notch to reduce cogging torque of interior type permanent magnet(: IPM) motor. Through Fourier formulation of magnetic field on rotor, we found position of notch and manufactured armature that is designed by optimizing analysis. The validity of the proposed design is confirmed with experiments.
