Design Study on Light-weight Quasi-coreless SPMSM using CFRP, Small Amount of SMC Core and Aluminum Winding

This paper presents design study on a lightweight quasi-coreless surface permanent magnet synchronous motor (SPMSM) employing Carbon Fiber Reinforced Plastics (CFRP) as the stator body to make it lighter. Stator body is composed of CFRP, a little soft magnetic composites core and aluminum winding for high power density. The design procedure for lightening the quasi-coreless SPMSM and experimental drive performance evaluation results are reported. Finally, remaining issues which have been founded are discussed.
