摘要： A cooling gas ventilation circuit is provided for an end winding of a rotary machine having a rotor of the type having a plurality of radial slots and a plurality of coils respectively seated in the radial slots, the coils extending beyond a pole face of the rotor to form the end winding. The ventilation circuit is composed of first and second cooling gas passages, respectively defined in at least one turn of each coil of the end winding. Each first cooling gas passage extends from an inlet port in communication with a cavity on one longitudinal side of the turn to an exit port defined on the other longitudinal side of the turn. Each second cooling gas passage extends from an inlet port in communication with the cavity on the one longitudinal side of the turn to an outlet in the form of a radial chimney defined through a plurality of the turns of the coil within the respective radial slot. In the presently preferred embodiment, the second passage is longitudinally offset in the coil structure with respect to the first cooling passage, so that they serve to cool respective portions of the coil. The passages may be but are not necessarily defined in the same turn of their respective coil.

摘要： Cooling of the rotor endwindings in a dynamoelectric machine is improved by providing radially-extending ducts in the spacers located between the concentric end turns of the rotor winding. The ducts have an inlet located near the radially inward end of the spacer and an outlet located near the radially outward end of the spacer. The inlet can be formed on either an axially-oriented surface of the spacer or a circumferentially-oriented surface of the spacer. The ducts direct cooling air into the cavities between the end turns in such a manner that the circulation velocity in the cavities is increased. This results in increased heat removal capability.
