“…Three machine types (SRM, SCIM, and PMSM) are compared in Table IV, based on their typical relative torque and power, to weight ratios [34]. In Table IV, the SRM has the highest torque to weight ratio, but the power to weight ratio suffers because of a compromised base speed due to the inability to force sufficient current into (or from) the machine at higher speeds (power = torque x speed).…”

This paper proposes a new asymmetric neutral-point diode-clamped (NPC) multilevel converter for a four-phase switched reluctance motor drive. The inbuilt NPC clamping capacitors are used for both voltage level clamping and also as dc rail voltage-boosting capacitors to increase the output power of the motor, particularly for high-speed electric vehicle applications. The new converter allows regenerative energy to be recovered back to the dc supply for rapid machine braking, thus increasing overall drive efficiency. Analysis of the different modes of converter operation, along with design equations for sizing the voltage-boosting capacitors, are detailed. The effect of capacitance on boost voltage and increased motor base speed is presented. Simulation and experimental results confirm the effectiveness of the proposed converter.

A novel structure of switched reluctance machines (SRMs) is proposed in this study. The proposed structure uses the advantages of the axial flux path, short flux path, segmental rotor, and flux reversal free stator machines all together to improve the torque density of the SRMs. The main geometrical, electrical and physical specifications are presented. In addition, some features of the proposed structure are compared with those of a state-of-the-art radial flux SRM, considered as a reference machine. Achieved results reveal that, compared with the reference machine, the proposed machine delivers about the same torque, albeit employing considerably lower volume and active material mass. These make the proposed structures a potentially proper candidate for traction and propulsion applications demanding high-torque density machines.

“…Automotive traction application necessitates higher torque density, performance, reliability, better fault tolerance and lesser costs. SRMs define their advantages with these criteria compared to an induction motor or a rare earth motor [1] [2]. However, a wide acceptance of SRM is limited in the automotive field owing to its weight, torque ripple and acoustic noise unlike other type of motors of the same rating [3].…”

There is a growing interest in developing Switched Reluctance Motors for electrical traction applications. This is mainly due to the significant advantages as lower cost, better fault tolerance, high reliability possessed by Switched Reluctance Motor (SRM) when compared with any other rare earth motors. But the SRM suffers from a torque ripple problem due to its double saliency and this has limited its use in automotive traction applications. This paper deals with the design of an 8/6 20kW SRM used for electric vehicle application and comparison of performance of the conventional motor with that of geometrically optimized SRM. The conventional design method is available in literature. The optimized geometry is modeled using JMAG software and compared with the conventional one for reduced torque ripple. The optimization was done for the air gap, extended pole shoe, fillets and circular windows for reduced torque ripple. The simulation shows a reduced torque ripple for the optimized geometry.
