Abstract :
The practical considerations for a 50,000 rpm switched reluctance machine (SRM) are studied in this paper. A novel rotor design topology with a flux bridge is proposed to reduce the windage losses at high speed. The electromagnetic characteristics of this design are analyzed in this paper. In addition, the practical problems of fabricating the prototype and testing it at high speed are discussed. Finally, experimental results are presented and compared with FEA simulation results.
