“…where J is the rotational inertia, ω is the rotational angular speed, T e is the electromagnetic torque, T L is the load torque, T 0 is the additional torque including friction torque, air resistance torque, etc. In [11] the authors designed and optimized a 12/8 SRM for EVs and hybrid EVs (HEV). Owing to their optimization method, the torque ripple is reduced by 10.2% and the average torque is increased by 2.4% compared to a typical benchmark design.…”

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

“…In order to meet the demand, now a days there is more attention in the low cost switched reluctance motor drive system because of several advantage such as robust construction, normally cheap, design simplicity, no winding on rotor and absence of demagnetization which is the most suitable for electric and hybrid electric vehicle [14,22,[26][27][28][29][30].…”

The application of permanent magnet free motors have gained a huge attention for pure electric and hybrid electric vehicles. This paper proposed the design of 20-kW switched reluctance motor having 18 stator poles and 12 rotor poles by using finite element analysis machine design software Infolytica magnet and the main focus is to achieve the high speed, torque with adequate performance for electric vehicles. The asymmetric bridge converter has been used and the series of varying the excitation voltage, slot fill factor with respect to the number of turns and stranded area of the conductor has been analysed. Additionally, in order to the electromagnetic force vector, the switching sequence is examined. The simulation results show the great potential of the suggested motor and can provide a good starting torque with high speed and can be suitable to achieve the freedom Car 2020 electric vehicle target.

“…It is not easy to obtain excellent torque performance based on traditional control strategies and industrial use of SRMs has been slow due to its higher torque ripple. In order to obtain better torque performance, the domestic and foreign researches in recent years mainly focus on two ways: the first is to optimise the shape or size of the stator and rotor to minimise the torque ripples [4–6]; the other is taking different control strategy to improve the torque performance without changing motor structure. In [7, 8], by establishing a torque sharing function (TSF), the minimum torque ripple can be realised.…”

In this study, a DC‐biased sinusoidal excited control method is proposed for a traditional four‐phase switched reluctance motor (SRM). Based on the proposed method, the torque ripple is smaller than that of traditional square excitation. First, the mathematical model of four‐phase SRM with DC‐biased sinusoidal excitation in dq‐axis rotating coordinate system is established and the instantaneous torque is analysed. It is found that the torque is proportional to q‐axis current and does not contain reluctance torque component with DC‐biased sinusoidal excitation for four‐phase SRM. Then the current control methods for torque component and magnetic field component are studied. The torque component is controlled by the sinusoidal pulse‐width modulation (PWM) method, and the magnetic field component is controlled by the current hysteresis tracking method. Finally, the proposed method is verified by finite element simulation and experiment results. Compared with the square wave excitation, the torque ripple is reduced by about 40%.
