This paper deals with a study on characteristic of inductance on spoke type motor. The rotor and stator is redesigned as rounding teeth of stator and pole surface of rotor. Result, a shape of air-gap is changed and the cogging torque is reduced greatly. In consequence, the inductance of spoke type motor is changed. The Finite Element Analysis(FEM) is used to characteristics.

This paper presents a novel method for cogging torque reduction of interior type permanent magnet motor. For calculation position and width of notch, energy formulation and cogging torque function in air gap are analyzed by analytical method(space harmonics method) and numerical method. The optimal shape of notchs is decided by using finite element method. The validity of the proposed method is confirmed with experiments.

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.

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.

This paper presents normal force analysis and its minimization of synchronous permanent magnet planar motor(SPMPM) with Halbach array. Firstly, the experimental error of thrust is investigated and it is caused by the friction force generated by normal force. Then normal force is analyzed by Maxwell stress tensor. At last, the normal force is minimized by using genetic algorithm and it is decreased from 672.83[N) to 144.24[N] remarkably.
