As a switched reluctance motor with simple structure, a two-phase switched reluctance motor (SRM) has the advantages of the above. In contrast, the complexity of the motor structure and the manufacturing cost are low, and only one-way operation is required. The control strategy is simple. Based on the analysis of the self-starting mechanism of the two-phase switched reluctance motor with variable air-gap rotor structure, the structure scheme of the variable airgap rotor is determined by the finite element method. Two-dimensional model of two-phase switched reluctance motor with vertical air gap structure. To minimize the electromagnetic torque ripple, the structure parameters of the motor such as air gap, stator-rotor pole arc and winding turns are optimized. To solve the finite element optimization simulation time process, a numerical batch interpolation method is developed to optimize the non-uniform pole arc of the rotor to improve the finite element simulation speed. Finally, the fixed-rotor pole arc and winding turns of the motor are optimized. The motor parameters are further optimized to make the static performance of the motor more stable.
