| Abstract: | In this paper, a novel direct-driven wheel permament magnet brushless DC motor using for electric vehicles is designed. The Proposed motor is specical for its exterior rotor structure,which can be fitted with a wheel tire to realize the direct drive for each wheel of an EV without any mechanical transmission.Then it can be operated in low-speed,high-torque,and high efficiency.The paper's emphasis lies on the analysis of magnetic flux,magnetic induction intensity and torque with the aid of finite-element electromagnetic field analysis. |
