    Abstract: This research designed an operating mechanism for a double-stator permanent magnet brushless DC motor to meet the load characteristics requirements of a 126 kV high voltage circuit breaker. The new design could help reduce the volume of the driving motor of the operating mechanism of a high voltage circuit breaker, improve operational reliability, and implement the force analysis of the load side.Besides, this paper studied the structure and main parameters of the driving motor, including the vital size of the motor, pole arc coefficient,electromagnetic load, stator slot number, and stator split ratio. In addition, it employed the finite element method to establish the driving motor model and obtain the magnetic cloud distribution, magnetic force line distribution, output torque, and current of the motor.It also analyzed the electromagnetic properties and dynamic characteristics of the motor. The result verified the rationality of the motor design.
    Key words: high voltage circuit breaker; double stator permanent magnet brushless DC motor; operating mechanism
