Abstract
Official abstract text for this publication.
Turbomachinery comprising first and second sets of rotors configured to operate on a working fluid. The machinery further comprises first and second sets of electric machines coupled to the respective first and second rotors, and a coupling arrangement arranged to couple adjacent rotors of the first and second rotor sets to provide for fixed ratio, contra-rotation of the first and second rotor sets.
First claim
Opening claim text (preview).
The invention claimed is: 1. Turbomachinery comprising: first and second sets of rotors of a contra-rotating compressor configured to operate on a working fluid; combustion equipment configured to mix fuel with the working fluid and combust a mixture of the working fluid and the fuel; first and second sets of electric motors coupled to the respective first and second rotors; a common motor controller configured to: control the first set of electric motors to impart rotational force on the first rotors; and control the second set of electric motors to impart rotational force on the second rotors; and a coupling arrangement arranged to couple adjacent rotors of the first and second sets of rotors to provide for fixed ratio synchronized contra-rotation of the first and second sets of rotors. 2. Turbomachinery according to claim 1 , wherein the turbomachinery comprises a turbine. 3. Turbomachinery according to claim 1 , wherein the coupling arrangement comprises a mechanical gearing arrangement, which mechanically couples rotors of the first set of rotors with an adjacent rotor of the second set of rotors. 4. Turbomachinery according to claim 3 , wherein the coupling arrangement comprises a contra-rotating epicyclic gearbox. 5. Turbomachinery according to claim 3 , wherein the coupling arrangement comprises a ring gear mounted to each of the first and second rotors and a pinion gear arranged to mesh with the ring gears. 6. Turbomachinery according to claim 1 , wherein each electric motor comprises a radial flux electric machine comprising a stator and a rotor. 7. Turbomachinery according to claim 6 , wherein the stator of each electric motor is provided radially inward of the rotor. 8. Turbomachinery according to claim 1 , wherein rotors of adjacent electric motors comprise a different number of magnetic poles relative to one another. 9. Turbomachinery according to claim 4 , wherein the contra-rotating epicyclic gearbox comprises a star gearbox.
