Abstrakt: Switched reluctance motors' (SRMs) implementation in electric vehicle drives are widely increasing due to several merits, such as a wide speed range, high torque density, and rare earth‐free characteristics, but it also has some drawbacks, such as more torque ripples, acoustic noise, and vibration, that hinder its usage in electrical vehicle applications. This paper introduces a novel geometry of rotor teeth of SRM, where two slots are inserted per each tooth of rotor to create rotor‐slotted tooth SRM (RST‐SRM). The novel topology aims to enhance the performance of SRMs, especially at high speeds. The overall performance of the RST‐SRM was carried out in addition to comparing it with performance of both stator‐slotted tooth SRM (SST‐SRM) and conventional SRM. The design parameters of the three models are the same and carried out by finite element tools (FETs) to obtain the magnetic characteristics, and the static analysis of the three models is compared. Dynamic performance was achieved by implementing the MATLAB Simulink package. The steady‐state and start‐up performance of the three models were obtained and compared. The performance parameters are estimated at various slot dimensions of the novel technique, in addition to studying the effect of conduction angles for three models. Finally, the efficiency, iron losses, and torque ripple maps of the three models are compared to simulate the scope of the work of electric vehicles. [ABSTRACT FROM AUTHOR]
