【Abstract】 This paper presents a novel multipolar permanent magnet synchronous motor which takes external rotor and can be used as brushless DC motor to drive electrical vehicles. The structure of this motor is introduced. In order to get the precise data, the finite element method is used to analyse the motor′s magnet field. Computer simulation and experimental results show that the motor works well and conforms to design demand.更多还原
