COMPUTER-SIMULATION AND ANALYSIS OF A NEW POLYPHASE MULTIPOLE MOTOR DRIVE

This paper presents a new configuration of high power density, high-ef ficiency polyphase multipole permanent magnet motor and its control sy stem. The mathematical model and simulation for this kind of motor dri ve are presented in detail. The motor is essentially a kind of brushle ss dc motor with novel arrangement of its magnet and winding. The cont rol system is virtually a dual closed-loop system with current control ler as inner loop and speed controller as outer loop. State-space equa tions are used for the mathematical model of the motor, and real-time simulation is applied for the controller and switching devices. The si mulation results are verified with the experimental results and shown to be very satisfactory.
