Abstract

and equipped with non-overlapping concentrated windings, is analyzed in this paper. Thus, there is reduced copper loss, resulting to improved efficiency. Basically, the analyzed machine is a doubly-salient stator-PM machine, with a rotor made of modulating steel ring. The analysis includes the open circuit and on-load characteristics of the developed machines. Furthermore, a quantitative comparison of the electromagnetic analysis of the machines having different winding topology is also detailed in this study. The investigation shows that the even-rotor pole machines are characterized by higher cogging torque as well larger torque ripple, relative to their odd-rotor pole counterparts, due to their high possession of harmonics.
