Design considerations for concentrated winding synchronous reluctance machines

This paper presents crucial design considerations for the application of concentrated windings to synchronous reluctance machines. Challenges for the application of concentrated windings to synchronous reluctance machines are examined. The tradeoff between a winding configuration with high winding factor and low space harmonic content is carved out. A new approach improving the performance of concentrated winding synchronous reluctance machines is presented. Therefore, a winding configuration which is prioritizing a low space harmonic content over a high winding factor is chosen. Finally, a machine using this new approach is designed and compared to previously published designs.
