This paper presents a comparative performance analysis of 4-kW axial flux permanent magnet synchronous machines (AFPMSMs) with and without a rotor core. The present study is intended for low-speed applications; however, the investigated machines are designed using an improved diameter-to-length method and their comparative performance is assessed using comprehensive electromagnetic finite element analysis. The results of this analysis suggest that the proposed coreless topology has the advantages of higher output power, higher efficiency, and lower iron or core losses compared to the conventional iron core AFPMSM.
