Computer simulation and analysis of a new polyphase multipole motor drive

This paper presents a new configuration of high power density, high-efficiency polyphase multiple permanent magnet motor and its control system. The mathematical model and simulation for this kind of motor drive are presented in detail. The motor is essentially a kind of brushless dc motor with novel arrangement of its magnet and winding. The control system is virtually a dual closed-loop system with current controller as inner loop and speed controller as 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.link_to_subscribed_fulltex
