Abstract

Fractional slot concentrated winding permanent magnet synchronous machines (FSCW PMSMs) are suited for low speed direct drive since they offer comparatively large number of poles, high torque density, and low torque ripple. This paper introduces feasibility study on FSCW PMSMs with consequent pole (CP) rotor for low speed direct drive. A 40 pole-48 slot FSCW PMSM with CP rotor is analyzed and characterized by extensive 2-D finite-element analysis. The analysis reveals the proposed topology can achieve good performance.
