Concentric ring generators

摘要

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.

主权项

1. 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.
