DESIGN OF SRM AND AXIAL FLUX SRM FOR ELECTRIC VEHICLES

    Motors for in-wheel electric vehicle applications should have high specific torque. In addition, these motors should be rugged, insensitive to vibration, and temperature variation. Therefore, the segmented rotor switched reluctance motor (SRM) could be an attractive alternative to permanent magnet-based motors, which are being used for this application. A limitation of SRM is that it requires full pitch winding for its operation. Since in-wheel motors have high diameter to axial length (D/L) ratio, SRM of these dimensions would be bulky and has high copper loss due to full pitch winding. In this design, a novel SRM and an axial flux SRM (AFSRM) with a toroidal winding arrangement are proposed. It has a single-stator, dual-rotor configuration with 12 stator poles, and 16 rotor segments on each rotor disc. Comparison between SRM and AFSRM with the configuration of three-phase with pole number 12/16 pole configuration is done using MatLab simulation based on the Power, Torque, Speed, Phase voltage, and currents.
