TURBOGENERATOR Russian patent published in 2008 - IPC F01D15/10 

FIELD: mechanical engineering; gas-turbine engines.

SUBSTANCE: according to invention, turbogenerator contains at least one electric machine built into turbine, rotor of turbine is installed on supports on active magnetic bearings, radial displacement pickups are mounted in supports being connected to control unit, electromagnets of active magnetic bearings are connected through control unit to power consumers. Active magnetic bearings are protected from both sides by magnetic seals. Station of turbine is made of magnetic soft material. Windings of electric motor are made on stator of compressor, and system of permanent magnets of compressor is secured on turbine rotor. Windings of electric generator are fitted on stator of turbine, and system of permanent magnets of electric generator is secured on turbine rotor. Windings of stator of electric generator are enclosed in one or several casings to which air or water cooling system is connected. Turbine can be made multistage, and windings of stator of electric generator are made, each, for independent connection to consumers through switch.

EFFECT: increased efficiency and reliability of turbogenerator.
