Abstract

© PEMD 2020. All right reserved.This theoretical study explores concepts of electrical windings in application to low-voltage permanent magnet (PM) machines. The research focus has been placed on low-power-loss winding designs, with the use of modern additive manufacturing (AM) techniques in mind. A case study PM machine with concentrated winding topology has been used to demonstrate how the AM enabled winding concepts compare with the more conventional constructions. To make the comparison more relevant, the theoretical body of work has been supported with the existing know-how in electrical machines construction and latest developments in AM. The research findings suggest that the AM winding concepts offer similar power losses with simpler winding fabrication and assembly, subject to further advancement in AM.
