Abstract :
Soft magnetic composites (SMC) are emerging in electrical machine design offering the potential for innovative machine geometries and lower cost manufacturing. This paper examines the design and analysis of a SMC-based radial-field fractional-slot concentrated-winding permanent magnet machine using 2D finite-element analysis. Its performance is compared with an existing conventionally-laminated, distributed-winding baseline design for two cases, firstly with the same active stack length and secondly with the same end-winding stack length.
