Multiphase induction machine for aero-engine shaft-line-embedded starter/generator: Scaled prototypes testing

摘要

The paper presents the experimental testing of two variants of scaled prototype (10 kW) of a four-three-phase fault tolerant induction machine to be installed on the high pressure shaft of an open rotor jet engine. The two machines have the same overall dimensions, but one machine adopts a conventional magnetic core made of thin laminated FeSi alloy while in the other one the rotor is made of FeCo. Starting from the classic experimental tests, the parameters of the prototypes are computed to determine and compare the electromechanical performance of the two solutions.
