Abstract

The paper describes a thermal model for a duplex three-phase induction machine for fault tolerant applications. Three-phase and six-phase variations of 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. Experimental validation is presented for load operating conditions.
