Abstract

This paper presents the design and analysis of two distinctive three-phase permanent magnet-embedded switched reluctance motors for electric three wheelers. The configurations used in this work are a 12/8 classic SRM and a 12/10 E-core stator SRM. For the configuration of the 12/10 E-core stator, horizontal alignment of the permanent magnets is introduced, and the magnets are placed on the stator auxiliary poles. In the case of 12/8 SRM, the permanent magnet is placed in the stator yoke. Initially, a dynamic calculation of the vehicle and the SRM design process are carried out to determine the power rating and the optimal design parameters. The motor performance analysis is carried out using finite element-based software with the acquired specifications. The comparative analysis is established by employing various magnet materials with the intention of achieving the same motor torque. Outcomes reveal that the configuration of the permanent magnet embedded in the 12/10 E-core stator SRM is able to generate the needed average torque with minimal cogging torque and torque ripple using low-cost ferrite magnets, making it suitable for electric three-wheeler applications.
