The synchronous electrical machine (8) comprises a machine housing (26) including a stator (27) and a rotor (28) lodged in the stator, the rotor being separated from the stator by an airgap (29), the machine housing being configured to dissipate thermal losses generated by the stator.The stator comprises stacks (30) of laminations (300) and at least one channel (36) extending along a longitudinal direction of the stator and formed in the laminations, two adjacent stacks of laminations being separated by pins or spacers (31) to form an extraction duct (32) connected to the channel, the machine housing further comprising an extraction opening (21) 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.
