Switched Reluctance Motors and Drive Systems for Electric Vehicle Powertrains: State of the Art Analysis and Future Trends

This paper presents a detailed literature review on switched reluctance motor (SRM) and drive systems in electric vehicle (EV) powertrains. SRMs have received increasing attention for EV applications owing to their reliable structure, fault tolerance ability magnet free design. The main drawbacks of the SRM are torque ripple, low power density, factor small extended speed range. Recent research shows that multi-stack conventional motors (MSCSRM) with segmental rotor (MSSRM-SR) promising alternative solutions reduce ripples, increase density factor. Different winding configurations such as single-layer concentrated (SLC), single layer mutually coupled (SLMC), double (DLC), (DLMC) fully-pitched (FP) introduced recent years average decrease ripples. analyzes methods structure SRMs, including rotors. They been compared assessed detail evaluation ripple reduction, torque/power increase, noise/vibration characteristics mechanical structure. In addition, various fully addressed drives, soft-switching drives standard inverters an integrated battery charger. this paper, control also reviewed classified. These include strategies fault-diagnosis, fault-tolerance techniques sensorless control. key contributions provide useful basis analysis modeling electromechanical design, systems, applications.
