� 2016 IEEE. Advanced design and operation consideration for the close-connected winding permanent-magnet brushless DC machine is proposed in this paper, including circulating current elimination, fault-tolerant control for the breakdown of a power electronic switch, and a sensorless control method. With the finite-element analysis, the influence of machine design parameters on circulating current is investigated. By properly controlling the status of power electronic switches, the coils being connected into the equivalent circuit can be changed to avoid the failure switch. Sensorless control is explored by detecting the zero-crossing point of electromotive force.
