| Abstract: | This paper proposes a high efficiency outer rotor type PM brushless DC motor. It is mounted directly on the wheel to use the motor torque directly as the driving torque so as to reduce the power transmission loss by eliminating transmission components such as differential gear and transmission gear and to obtain higher efficiency. From the theory of electric magnetic field, the paper presents also a method of reducing rippe torque and a conception flux weakening control in PM brushless DC motor. |
