This paper describes the design of a high-speed three-phase switched reluctance machine to drive a compressor for the air management of a fuel-cell system for automotive applications. The machine geometry is optimized by means of a finite-element method coupled to a genetic algorithm. The performance of the optimized machine is evaluated, taking into account the iron and air-friction losses. Some theoretical and numerical results are sustained by the measured ones in the same operating conditions.
