More Information
Summary: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.
