In parallel with the increased production of electric vehicles, the research on electric motors has become very popular. Switched Reluctance Machines (SRMs) have been widely preferred in these investigations. Mutually Coupled Switched Reluctance Machine (MCSRM) has higher torque performances than conventional SRMs have. In this study, it is aimed to reduce the weight of MCSRM by geometric arrangement. For this purpose, the MCSRM's stator yoke is minimized without deteriorating the flux distribution. Various geometrical changes are performed on the stator yoke of the MCSRM. Each of the obtained motor models is magnetostatic analyzed in different currents by finite-element analysis. From comparison of the results of the analysis, it is seen that the proposed MCSRM models show reduction in the stator volumes between 11.31% and 14.17%. This reduction leads to a reduction in the overall weight of the MCSRM.Index Terms-Mutually Coupled Switched Reluctance Machine (MCSRM), stator yoke, volume, weight. CIHAN SAHIN, is

Switched reluctance machines (SRMs) are of great interest because of their simplicity, low-cost, reliability, robustness, fault-tolerance and extended-speed constant-power operation. However, conventional SRMs suffer from high torque ripples. There exist several methods, which have been proposed to reduce torque ripples. One of the proposed methods is to change the geometric structure of the machine. However, analysis of the state-of-the-art designs show that, despite achieving favourable results in applications, the moulding pins of the machines are normally neglected. A motor that gives positive results may get affected negatively by its random moulding during its manufacturing. In this paper, mitigation of torque ripples in short-pitched SRMs (SPSRMs) and fully-pitched SRMs (FPSRMs) are investigated. Three-phase SPSRM and FPSRM are chosen for this study and the effects of the geometric points of moulding pins in the machines are studied comparatively. Maxwell 2D program is used for the analysis and two different models are compared for both SPSRM and FPSRM. The obtained results show that the torque ripples of the two machines are lower when moulding pins are closer to the rotor position. It is reduced by 2.56% at 10 Amps in the proposed SPSRM and 12% at 6 Amps in the proposed FPSRM. It is also observed that the applied method is more effective in reducing torque ripples of FPSRMs than SPSRMs.

“…Subsequent work [5][6][7][8][9][10] on Segmental Rotor SRMs has tended to focus on fundamental design changes, rather than optimisation of the basic design. In contrast, the research described in this paper has been undertaken to assess the improvements that the optimisation of these motors could bring to both fully pitched and single tooth wound machines.…”

Segmental Rotor Switched Reluctance Machines have been demonstrated to produce significantly more torque than Conventional Switched Reluctance Machines because each coil is able to link more magnetic flux. In previous work the range of topologies studied has been relatively restricted; there has been no consideration of the range of stator tooth and rotor segment number options and the designs have not been formally optimised in any way. This paper seeks to address this: using Finite Element toolsets for optimisation it describes the resulting machines -uniquely featuring a greater number of rotor segments than stator teeth. The paper assesses the credible tooth and segment options, with each option optimised to maximise torque capability. From this assessment conclusions are drawn which contrast each machine's performance based on criteria including torque production and loss. In order to validate this optimisation process, a prototype machine is built and its performance compared with these predictions.
