Abstract: An electrical machine to facilitate transporting fluids through a pipeline is provided. The electrical machine includes a rotor assembly that further includes an array of magnets configured to generate a distributed magnetic field. The rotor assembly has corrosion-resistant features that facilitates mitigating deleterious effects to the rotor assembly while being exposed to aggressive and harsh fluids.

Abstract: An electrical machine to facilitate transporting fluids through a pipeline is provided. The machine includes a stator, a rotor magnetically coupled to the stator, and a housing enclosing the rotor and the stator. The housing includes a wall that facilitates channeling a first fluid at a first pressure through a portion of the housing. The machine also includes a stator enclosure defined by at least one wall that facilitates maintaining a second fluid within the stator enclosure. The stator enclosure is positioned within the electric machine housing. The stator enclosure has at least one wall that substantially isolates the second fluid from the first fluid such that only the second fluid is in flow communication with the stator. The stator enclosure has at least one wall that facilitates heat transfer from the second fluid to the first fluid. At least a portion of at least one of the stator enclosure walls is configured to facilitate equalizing the first pressure and the second pressure.

Abstract: Support feet of a generator are mounted on foundation columns spaced laterally one from the other, with one column having a block in a recess for receiving the feet on one side of the generator. Guides on a radius and supported by the generator foundation extend through notches on the underside of the block. To locate an end of the generator displaced horizontally from the turbines, the generator is unloaded from the foundation and the block is removed. The generator is then loaded onto the guides and pivoted about a vertical axis to locate at least one end out of alignment with the axis of the turbines enabling removal of the generator rotor in an axial direction. By employing two blocks set in recesses in the opposite columns and sets of tracks which extend into the notches, the generator can be rotated about a vertical axis through its center to locate the generator rotor in axially non-interfering positions with the adjacent turbines.

Abstract: A method to start a combined unit gas turbine and electrical unit having a static start drive including the steps of: applying a variable frequency voltage from the static start drive to a winding of the generator to accelerate the combined unit to a turbine self-sustaining speed; accelerating the combined unit beyond the self-sustaining speed by applying torque generated by the turbine, and as the combined unit accelerates to a synchronous speed, applying a braking torque from the static start drive to steady the combined unit at the synchronous speed.
