In today's electrical drives, the use of more than three-phases to implement the electrical machine stator winding is a frequently adopted provision to enhance system power rating and fault tolerance. In VSI-fed electrical machines, multi-phase windings are adopted in both their symmetrical structures (with n equally distributed phases, supplied by a single(More)
1 Abstract—PM BLDC drives are utilized in a variety of applications because of their inherent features, and would be even more utilized if their torque performance could be improved. Indeed, when supplied with square-wave currents, the torque-speed characteristic undergoes a drop at high speeds and a significant torque ripple arises at both low and high(More)
