Homopolar motors are compact and, therefore, are attractive for use in a direct electric drive for a ship. Finally, the prototype of SM is made by the optimized size, and the SM is tested at a low temperature to obtain the critical temperature and critical current of the SM the experimental results verify that the designed SM can meet the requirements of SSG. The simulated results verify that the proposed optimal algorithm is feasible and effective.

Then, an optimal algorithm combining response surface methodology (RSM) and particle swarm optimization (PSO) is proposed to optimize the structure of SM in order to give full play to the advantages of SM. In addition, the influence of structural parameters of SM on the performance of SSG is analyzed by simulation. Second, the initial structural parameters of the SM are obtained by finite element method (FEM). First, a suitable superconducting material is selected to make SM by analyzing the characteristics and application background of the five practical superconducting materials, and the applicability and feasibility of the selected superconducting materials are demonstrated.
