摘要
A cooling gas ventilation circuit is provided for an endwinding of a rotary machine having a rotor and a plurality of coils seated in radial slots provided in the rotor. The coils each comprise a plurality of radially stacked turns, the coils extending beyond a pole face of the rotor to form an endwinding with longitudinal cavities between the coils. A substantially cylindrical baffle ring covers the radially innermost turns of the plurality of coils in the endwinding, and has a plurality of holes therein aligned with at least one of the longitudinal cavities between the coils.
