Abstract :
This paper describes a thermal model for a duplex three-phase induction machine for fault-tolerant applications. The three- and six-phase variations of the duplex three-phase machine operation under fault conditions are considered. Different winding configurations are investigated. Thermal analysis is performed using analytical and finite-element models. An experimental validation is presented for load operating conditions.
