Abstract

This paper deals with the considerations associated with the design of high-speed, high torque-density induction machines, to be used in elevated temperature environments. The considerations discussed are described by the design cycle iterations of an actual 9.5 kW machine, which runs at speeds of up to 75 krpm, with a rated torque density of 44 kNm/m³. Particular emphasis is made on the interaction (and conflict) of electromagnetic fields, thermal fields and mechanical constraints.
