Abstract

Ultra-high speed switched reluctance machines (SRM) are becoming more and more promising due to its robustness and simple geometry. This paper proposed a detailed design procedure for an ultra-high speed SRM, including dimension calculation, material selection, winding selection, windage torque calculation, drive system and control strategy. The ultimate goal is to build a machine that is electromagnetically good enough to rotate beyond 1,000,000 rpm. A Maxwell/Simplorer co-simulation model is built to validate the proposed design. Single pulse control is used to drive the machine. The machine is being built and will be finished in the near future.
