要約(英語): An axial-flux (or axial-gap) permanent magnet synchronous motor (AFPMSM) with a large D/L ratio and a high pole-pair number has the potential high torque density. It can be applied to in-wheel traction motor drives. However, AFPMSMs tend to have large torque ripple. This paper introduces the design and fabrication of a double-sided stator type AFPMSM with a three-phase fractional slot winding in an 18-slot/20-pole configuration to reduce the torque ripple. Each phase of this fractional slot/pole combination contains three continuously connected coils placed next to each other, enabling us to simplify the motor assembly by reducing the connecting process of the winding terminals. The operational principle of the proposed AFPMSM, calculation results obtained via the three-dimensional finite element method, and experimental results of a prototype are presented in this paper.
