Abstract
This paper presents a design notch to reduce cogging torque of interior type permanent magnet motor. As design notch on rotor of IPM motor, magnetic field from between rotor and teeth of state is changed. By reason of variation magnetic field, cogging torque is generated. 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.
