BIROTATING POWER GENERATOR Russian patent published in 2008 - IPC E21B47/22 H02K16/02 H02K5/12 

FIELD: mining; electricity.

SUBSTANCE: birotating power generator contains, at least, one attachment point, an external rotor with a birotating hydraulic turbine and excitation magnets, a stator with an excitation winding installed thereon and an electrical connector. The birotating power generator is characterised by that the magneto-permeable division walls are hermetically sealed by an inner chamber of the stator and an external rotor. Driven magnets of two face clutches are set on both sides of division walls. Upper middle rotor with the driven magnets and an inner shaft are concentrically installed on bearings made inside the external rotor. Leading magnets of face magnetic clutches are installed in front of magneto-permeable division walls inside the inner chamber of the external rotor. Driven magnets of face magnetic clutches are installed in front of magneto-permeable division walls inside the inner chamber of the stator. In this case, driven magnets of internal face magnetic clutch are placed on lower internal shaft, driven magnets of external magnetic clutch are placed on lower middle shaft and excitation magnets are placed on lower internal shaft.

EFFECT: increased power of generator; smaller diametric dimensions and weight.
