Abstract :
Dynamic characteristics of permanent-magnet brushless DC motors (BLDCMs) in the presence of reluctance variations are formulated and analyzed. The local dynamics are presented, since a high percentage of currently available BLDCM systems are accompanied with linear velocity and current controllers. The notion of an equivalent DC motor model is presented, and its validity is examined
