Abstract: Provided is a synchronous electrical machine that includes a stator and a wounded rotor, the stator having a plurality of phases, each phase comprising coils connected together and magnetic stator poles cores fixed on a stator frame and evenly distributed along a stator diameter, each coil being wounded around a different magnetic stator pole core to form a magnetic stator pole, each phase comprising a same number of magnetic stator poles, the magnetic stator poles of each phase being disposed in the stator frame to form a concentric winding stator. The rotor includes a plurality of magnetic rotor pole cores evenly distributed around the rotor and rotor coils, each rotor coil being wounded around a different magnetic rotor pole core to form a magnetic rotor pole.

Abstract: Provided is a synchronous electrical machine that includes a machine housing having a stator and a rotor lodged in the stator, the rotor being separated from the stator by an airgap, and the machine housing dissipating thermal losses generated by the stator. The stator having stacks of laminations and at least one channel extending along a longitudinal direction of the stator and formed in the laminations, two adjacent stacks of laminations being separated by pins or spacers to form an extraction duct connected to the channel, the machine housing further having an extraction opening so that a fluid injected in the air gap at the ends of the stator flows in the extraction duct and in the channel, and is extracted from the machine through the opening to cool the stator and the rotor.
