An investigation on brushless DC motor CAD

Wang Qunjing; Li Guoli; Sun Mingshi; Kong Fanrang; Feng Zhihua

BLDC motors are widely used in industrial applications in the world, the design of the motor and its control circuits are related to each other, and it implies the complexity of BLDCM. A BLDC motor is a permanent magnet motor, the design methods are much different from that of traditional motors. The paper describes an investigation on design and analysis of BLDCM by use of a finite element method combined with a magnetic-equivalent-circuit method, it shows that the results are correct.
