Performance and manufacturability tradeoffs of different electrical machine designs

Abstract

This work addresses the manufacturability challenges in traction machine production systems and design. The tradeoffs between performance and manufacturability of a heavy duty traction machine for buses and trucks, are investigated for four different winding designs, with multiple stator combinations, all using the same interior permanent magnet rotor. We present an analysis of electromagnetic, thermal, cost and production system performance for 6 primary combinations.
