Evaluation of axial SRM for electric vehicle application

[Display omitted] •Axial switched reluctance motor is studied for automotive application.•At the same volume, axial SRM has lower average torque compared to the radial one.•To increase the average torque of axial SRM, its masse and volume must be increased. In this paper, a study on an Axial Switched Reluctance Motor (ASRM) is provided and comparisons with an equivalent Radial Switched Reluctance Motor (RSRM) are established. A 3D Finite Element (FE) model is used for the ASRM and only 2D FE model for the radial one in order to reduce the computation time. First, a bibliographic review and descriptions of the two motors are given. Secondly, comparisons between both structures are proposed including flux linkages, developed torques, masses, torque-speed curves and cartography of minimum torque ripples. In order to make the comparisons more reliable, optimized control parameters and full operating range for electric vehicle (EV) power train are taken into account.
