초록

The invention relates to a turbomachine of axis X including a compressor and an integrated starter/generator. The field magnetic circuit of the starter/generator is mounted in the bore of at least one disk of the compressor and surrounds the secondary magnetic circuit which is secured to a cylindrical shroud provided on the support structure for the bearing of the compressor. The invention applies in particular to single-shaft or multi-shaft turbomachines.
