Patent ID: 6914344

Claim:
A turbomachine comprising a combustion chamber and a high pressure shaft, said shaft presenting upstream from said chamber an axial compressor of axis X for delivering air to said chamber, and downstream from said chamber, a turbine receiving hot gas from said chamber for rotating the rotor of said compressor, said compressor having a plurality of compression stages, each stage presenting a ring of stationary blades secured to a casing and a ring of moving blades projecting radially from the periphery of a disk of said rotor, said turbomachine further comprising an electricity generator coaxial with said body and having a field magnetic circuit constrained to rotate with said rotor and a secondary magnetic circuit secured to said casing, the field magnetic circuit being mounted in the bore of at least one disk of said compressor and surrounding the secondary magnetic circuit, and the generator being configured to operate as a starter of said turbomachine, wherein the compressor includes at least one disk carrying moving blades of large chord, and the field magnetic circuit is mounted in the bore of said disk.
