A New Partitioned Stator Machine with Halbach Permanent Magnet Array
2016 IEEE Vehicle Power and Propulsion Conference (VPPC), 2016The partitioned stator (PS) machine allows the windings and permanent magnets (PMs) to separate, avoiding the crowded space in the stator. In this paper, a new PS-PM consequent-pole machine is proposed, in which Halbach PM array is designed. For evaluation, the proposed PS-PM machine is compared with two existing PS-PM machines, namely the consequent ...
