Computer Simulation and Analysis of a New Polyphase Multipole Motor Drive

摘要

This paper presents a new configuration of high power density, high-efficiency polyphase multipole 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 con- troller as inner loop and speed controller as outer loop.
