| 20100019591 | HEAT TRANSFER ENHANCEMENT OF VENTILATION CHIMNEYS FOR DYNAMOELECTRIC MACHINE ROTORS - A cooling gas ventilation chimney is provided for enhancing the heat transfer of an end region of a dynamoelectric machine. The dynamoelectric machine includes a rotor having a plurality of radial slots. A plurality of coils are seated in the radial slots, and the coils form a plurality of radially stacked turns. The ventilation chimney includes one or more chimney slots defined in at least a portion of the radially stacked turns. The chimney slots extend in a substantially radial direction to the rotor, and some of the chimney slots have an axial or circumferential length different from other chimney slots. | 01-28-2010 |
| 20100096937 | HEAT TRANSFER ENHANCEMENT OF DYNAMOELECTRIC MACHINE ROTORS - A rotor is provided for a dynamoelectric machine having one or more windings. The windings have one or more turns, and the turns have one or more outlet ducts that are located near a chimney. When the outlet ducts are stacked one on top of another, they form substantially radially oriented passages. The heat transfer performance of a portion of the rotor can be improved by locating two or more circumferentially spaced radial ducts near the chimney. A chimney can also be formed of one or more chimney slots defined in at least a portion of the turns, where one or more chimney slots extend in a substantially slanted direction to a radial direction of the rotor. A transition region of the rotor can also include one or more diagonal flow channels, which discharge into one or more chimneys. | 04-22-2010 |

| 20090309431 | APPARATUS FOR USING AN ELECTRICAL MACHINE TO TRANSPORT FLUIDS THROUGH A PIPELINE - A stator for an electrical machine includes teeth assembled from a plurality of stacked laminations mounted on a cylindrical protective surface thereby forming a plurality of slots. The stator also includes an armature winding assembled within the teeth by inserting components of the armature winding into the plurality of stator slots from positions external to the teeth in a manner that facilitates mitigating potential for coil distortion. The armature winding includes a plurality of coils that each include an end winding. The stator further includes a segmented yoke inserted around the armature winding in a manner that facilitates mitigating a potential for disturbing the end winding of the coils. Independently assembling the stator components in this manner facilitates varying a thickness and/or the number of heat conducting laminations between the yoke and teeth that subsequently facilitates heat transfer from the armature winding to an outer pressure casing of the machine. | 12-17-2009 |
