Improved Performances of a PMSM with Reduced Torque Ripples, Optimized Based on Hybrid Algorithm, Dedicated for Light EV

This paper deals with the optimum design of a permanent magnet synchronous machine (PMSM) used for the propulsion of a light electric vehicle. The optimization is employed based on evolutionary algorithm by combining the simulated annealing with the particle swarm approach. The optimized solution is validated numerically through finite element method (FEM). Furthermore, a prototype of the optimized machine is constructed and the control of the motor operation is tested, showing that the obtained results are validating the employed approach and the prototype corresponds to the application needs.
