Abstract
A rotating machinery equipment is disclosed, including a rotating electrical machine having a stator () and a rotating shaft (), whereon a rotor () is mounted. The machinery equipment further includes a cooling fan () comprised of a rotating impeller () mounted on the rotating shaft () for co-rotation therewith. Cooling gas passages () are provided for delivering compressed cooling gas through the stator and rotor. The cooling gas is delivered by the impeller () into a cooling-gas distribution chamber (). The pressure of the cooling gas in the cooling-gas distribution chamber generates an axial force balancing the axial thrust generated on the electrical machine by the cooling gas flow.
