| Outline of Final Research Achievements |
In this study, a high efficiency ferrite magnet motor having a toroidal winding stator and a 3 dimensional (3D) magnet arrangement rotor is proposed. The toroidal winding method can produce the magnetomotive force distribution equivalent to distributed winding method with a high winding space factor. The proposed toroidal winding method can reduce the winding resistance and the copper loss of the motor. To improve the output torque of the motor, 3D arrangement ferrite magnets is used for the rotor. As a results, it was clarified that the proposed motor can improve the motor efficiency compering conventional ferrite magnet motor.
