Abstract

This paper presents the detailed design and finite element study of a synchronous reluctance machine with a non-overlapping fractional slot concentrated windings. The machine design employs single tooth wound coils with short end windings and high fill factor, which facilitates the machines high torque density and efficiency. As no magnets are required, the machine is low cost and of robust construction like the induction motor. This machine topology is presented as a step forward in synchronous reluctance technology which are usually wound with a distributed winding with long end turns. Analytical design methodologies and performance through finite element studies are presented. Scaling and design options, along with manufacturing options are discussed, the future development of the topology for automotive traction and other demanding applications is also presented.
