Abstract: The analytical method was used to establish the coil assisted stator excitation switched reluctance motor nonlinear model, and the sensitivity analysis of the key structural parameters of the motor was carried out. The beetle antennae search algorithm was applied to the multi-objective global search of the motor to solve the structural parameters with the best performance. In order to verify the effectiveness and feasibility of the beard algorithm, the particle swarm algorithm was also used to optimize the motor with multiple objectives, and the three-dimensional finite element model of the motor optimized by the two algorithms was established. The comparative analysis of the two optimization results shows that the motor torque ripple obtained by the optimization of the beetle antennae search algorithm is smaller and the efficiency is higher.
