Abstract

Electric vehicles (EVs) offer several advantages over internal combustion engines (ICE), including high energy efficiency, noise reduction, low maintenance, and a wider speed range. This results in lower fuel consumption, reducing dependency on oil imports and enhancing energy security. The motor drive is a critical component of EVs, providing the necessary propulsion force. This paper presents a comprehensive comparison of state-of-the-art motors suitable for EV applications, including DC motors, induction motors (IM), brushless DC motors (BLDC), permanent magnet synchronous motors (PMSM), and switched reluctance motors (SRM). Various design aspects relevant to traction applications, such as cost, reliability, efficiency, torque, fault-tolerance ability, excitation arrangements, and power density are also addressed. The performance of an EV based on the SRM drive is analyzed using MATLAB Simulink, with a special focus on parameters like speed, torque, flux, and state of charge (SOC). The review highlights that SRM drives have significant potential in EVs due to their reliable structure, fault tolerance capability, and magnet-free design. However, their application in EVs is currently limited due to torque ripples, as evident from the simulations. This paper is expected to serve as a foundation for further enhancing the performance of SRM drives for EV applications.

Abstract

The switched reluctance motor (SRM) offers extensive prospects, particularly within the realm of electric vehicles (EVs). Its robust construction, wide speed range, high torque density, and efficiency provide significant advantages that surpass other motors. Nonetheless, controlling these motors is more intricate when compared to conventional DC brushed or AC motors. This complexity arises due to the non-linear inductance characteristics of SRMs, resulting in undesirable effects like torque ripple, vibrations, and noise. Using the conventional full-bridge inverter, three switching approaches are highlighted for various operating modes of an EV. This aims to reduce costs and the number of switching pulses, leading to a more compact system, elimination of dead time, and switching losses. The MATLAB/Simulink platform was utilized to examine the operational effectiveness of a three-phase 6/4 poles SRM drive. Additionally, this paper focuses on mitigating torque ripple concerns by employing an adaptive neuro-fuzzy inference system (ANFIS) controller that has better efficiency and superior responses compared to conventional controllers such as fuzzy logic control (FLC) and proportional integral (PI) control. The results of the simulation encourage the practical implementation of the system, which is the next step in the author’s research.
