Abstract: In the paper, the Wind Driven Optimization WDO algorithm is applied to the optimal shape design of a class of switched reluctance motors. The goal of the optimization is to identify a class of geometries which maximize the torque and simultaneously minimize the iron losses of the motor. Because of the twofold design criterion, the multi-objective version of the wind driven algorithm M-WDO is used. Results are eventually compared with those obtained by means of a standard genetic algorithm GA. For construction of optimized model of switched reluctance (SR) motor measurements of resistance and inductances vs. rotor position of commercial motor made of steel and non-optimized model motor made of soft magnetic composite were measured. On the basis of changes in inductance, electromagnetic torques were calculated. Results of B = f(H) and iron loss measurements of soft magnetic composites made of Somaloy 700 and Somaloy 700 HR powder are also shown which will be used for construction of optimized SR model motor.
