A new configuration for a high-power-density, high-efficiency polyphase multipole permanent magnet motor and its control system are presented. The mathematical model and simulation for this motor drive are presented in detail. The motor is essentially a kind of brushless DC motor with a novel arrangement of its magnet and winding. The control system is virtually a dual closed-loop system with a current controller as the inner loop and a speed controller as the outer loop. State-space equations are used for the mathematical model of the motor, and real-time simulation is applied for the controller and switching devices. The simulation results are verified with the experimental results and shown to be very satisfactory
