Simulation of the brushless DC machine

Research efforts on the brushless DC machine (BDCM) have produced a computer simulation model of the machine applicable for analysis of the machine during fault conditions. Several failure modes have been studied using this simulation technique. Modeling the motor during flux weakening, bearing failure, armature winding open circuiting, and armature winding short circuiting along with the operation of the machine under normal conditions is presented. This simulation model will facilitate further study of the BDCM and its utilization in the electromechanical actuation and control application.<
