A shaft (14) is formed with a magnetically transparent portion within its length, so as to enable passage therethrough of electromagnetic flux from stator poles, to a further shaft (20) to cause shaft (20) to move to a position in space, coaxial with the shaft (20).
[ What is claimed is:] [1.]1. A multi-shaft gas turbine engine in which co-axial, relatively rotatable inner and outer shafts drivingly respectively connect a first turbine stage with a first compressor stage and a second turbine stage with a second compressor stage, the co-axial shafts are supported by electromagnetic bearing means, and an assembly for placing an axial thrust on the inner shaft with an electrical stator means for electro-magnetically supporting the shafts for rotation, wherein the inner shaft has a radially extending magnetic flange por...
