N2 - The features of axial-flux switched reluctance motors include simple construction, robustness, rigidity, permanent magnet (PM) free, etc., making them a suitable candidate for various applications. In this paper, a novel placement of the yoke in the rotor of axial-flux switched-reluctance motors (SRMs) is introduced. The proposed rotor includes radial-yoke structures rather than the conventional axial yoke, which offers reduced axial length and weight. It was found that despite a reduced average torque and increased torque ripple, the torque density and efficiency are improved due to reductions in volume and losses. Given the absence of an inner shaft and offering the opportunity for using the rotor as a replacement for the rim, the proposed topology is a suitable candidate for in-wheel electric transportation such as bicycles, where shorter axial length and higher torque density are desirable.
