Abstract-The paper presents a simple nonlinear model of the switched reluctance motor (SRM) which requires a minimum of precalculated or measured input data. Therefore, it is convenient for use in earlier stage of SRM design in order to minimize time for finding optimal configuration. Moreover, it is shown that this model produces accurate torque shape for given current, and accurate flux linkage-current relationships. This also provides reliable results in dynamic regime. The simulation and experimental results are compared for available three-phase 6/4 motor.

Structural design optimization of 12/8 switched reluctance motor using single objectives genetic algorithms is explored. The objective of this optimization is to maximize the output torque using four parameters, namely rotor width of tooth root, rotor width of tooth tip, half of stator tooth width, and stator outer diameter. The result is the optimized motor has higher average torque of 25% compared to the initial design. The evaluation of motor model is finite element method. The 12/8 switched reluctance motor will be applied in a mini electric vehicle.

“…The effect of different design parameters on torque ripple in SRM and the design approaches to minimize torque ripple have been discussed in detail by Iqbal Husain. The sensitivity of geometrical parameters on the performance of SRM has been described in the literature [7][8][9][10][11]. In [10], the sensitivity of the stator and rotor pole arcs is studied to determine optimum pole arc configuration to minimize torque ripple.…”

-A major problem in Switched Reluctance Motor (SRM) is torque ripple, which causes undesirable acoustic noise and vibration. This work focuses on reducing the undesirable torque ripple in SRM by modifying stator and rotor geometry. This paper presents a comparative study on torque ripple minimization in SRM with modified pole shapes such as stator pole taper, stator pole face with non-uniform air gap and pole shoe attached to rotor pole. Further this paper presents a detailed sensitivity analysis of the effect of different geometrical parameters that alter the pole face shapes on the performance of SRM. The analysis is performed using finite-element method considering average torque and torque ripple as performance parameters. Based on the analysis, a design combining stator pole taper with non-uniform air gap is proposed to improve the torque characteristics of SRM. The dynamic characteristics of the proposed design are simulated and the results show satisfactory reduction in torque ripple.
