Abstract: This paper presents and compares two permanent magnet vernier (PMV) motors with fractional slot concentrated windings (FSCWs) and integral slot distributed windings (ISDWs). The ISDW PMV motor is newly proposed and optimized for a fair comparison with the existing FSCW one. The equations of back electromotive force of both motors are investigated and derived showing that the ISDW PMV motor has the potential to obtain higher torque capability. Also, their electromagnetic performances, such as torque capability,… Show more

“…It is evident that for the machine, the total PM loss accounts for a small part in the total loss (0.73%); the copper loss accounts for a considerable proportion in the total loss (84%); and, the dominant iron loss is concentrated on the stator. Without considering the friction, windage and stray loss, the efficiency of the proposed machine can be evaluated by the formula below [37],…”

“…According to the field-interaction principle, it is reasonable to think that the one with two PM pole has two winding poles, and the other with four PM poles has four winding poles, demonstrating the identical stators can have different winding poles. However, in quite many studies, the FSCW-PM vernier machines built upon the previous rule have been proposed under the assumption that three slots of a FSCW machine make up one winding pole pair [6][7][8][9][10]. This assumption is obviously useful as well as convenient to design the vernier machine, but there is still uncertainty whether the conventional rule under the assumption provides every available slot-pole combinations for the vernier machine.…”
