Finite-element analysis and design of a radial-field brushless PM machine utilizing soft magnetic composites

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.
