Abstract
A concentric generator usable with a gas turbine engine having a shaft. Disclosed embodiments include a generator with a rotor integral with the gas turbine shaft and a stator mounted concentrically with respect to the rotor. The stator may be mounted inside the turbine engine housing, or outside the turbine housing. In some embodiments, both the rotor and stator are mounted outside the turbine housing and rotation of the turbine shaft is translated to the rotor via a transmission.
Claims18
A generator comprising:
- a turbine engine comprising a shaft, a compressor, and a turbine;
- a rotor in mechanical communication with the shaft and configured to be rotated by motion of the shaft;
- a stator comprising at least one coil wherein the stator is disposed radially outward of the rotor and wherein rotation of the rotor within the stator causes the generation of electric power;
- positioning means for moving the at least one coil;
- and
- wherein the positioning means enables the at least one coil to move radially with respect to the rotor during rotation of the rotor and wherein the radial movement of the at least one coil during rotation of the rotor changes a voltage of the generated electric power.

A method of manufacturing a generator comprising:
- connecting a rotor in mechanical communication with a shaft of a turbine engine so that the rotor is rotated by motion of the shaft;
- positioning a stator comprising at least one coil radially outward of the rotor, concentric with the rotor and the shaft of the turbine engine, and wherein rotation of the rotor within the stator causes the generation of electric power;
- providing positioning means for moving the at least one coil;
- and
- wherein the positioning means enables the at least one coil to move radially with respect to the rotor during rotation of the rotor and wherein the radial movement of the at least one coil during rotation of the rotor changes a voltage of the generated electric power.

A concentric generator comprising:
- a turbine engine comprising a shaft, a compressor, and a turbine;
- a rotor, mounted concentrically with the shaft, and in mechanical communication with the shaft wherein the rotation of the shaft causes rotation of the rotor;
- a stator comprising at least one movable coil positioned concentrically and radially outward of the rotor and wherein rotation of the rotor within the stator causes the generation of electric power;
- positioning means for moving the at least one movable coil;
- and
- wherein the positioning means enables the at least one moveable coil to move radially with respect to the rotor during rotation of the rotor and wherein the radial movement of the at least one movable coil during rotation of the rotor changes a voltage of the generated electric power.
