Evaluation of DC Excitation of External-Rotor-Segment-Type SRM for Power Generation

We evaluate an external segment-type switched reluctance motor (ESSRM) generator via simulations and experiments on actual ESSRM. In the simulation, shape of ESSRM was optimized using a genetic algorithm with two sizes varied as parameters. As result calculating 480 different shapes, it is found that model by has 1.45% higher power generation efficiency 95.08% 634W generated 2,896W than single parameter. To prototype small SRM for evaluating validity simulation model, ESSR similarly miniaturized. developed conducted experiments. ESSRM, maximum measured 62.13% when 81.20W. comparing results experimental changing number segments, consistently highest segments five in both simulations. The confirm model.
