Patent ID: 8133004

Claim:
Jet engine, with at least one hollow shaft and/or low pressure shaft rotatably supported in at least one bearing arrangement about a center axis, on which shaft at least one compressor as well as at least one turbine is arranged, whereby the jet engine comprises an electromechanical unit centrally arranged about the center axis, which electromechanical unit is embodied as a starter and/or a generator, and whereby the electromechanical unit is further embodied as an active magnetic bearing arrangement, which supports the hollow shaft and/or low pressure shaft, characterized in that the electromechanical unit is embodied as a transverse flux machine, wherein the electromechanical unit comprises a rotor carrying permanent magnet segments, and further comprises a stator having a profiled stator surface, and wherein the rotor moves about the stator, whereby the profiled stator surface, which stands below the permanent magnet segments rotating thereover, is embodied wave-shaped with stator surface peaks.
