HYBRID ELECTRIC MACHINE-GENERATOR Russian patent published in 2017 - IPC H02K47/04 H02K51/00 H02K49/08 

FIELD: electricity.

SUBSTANCE: this invention can be used as an electromechanical mechanical energy converter fed to one (mechanical) input of the machine, and direct current electric power supplied to its other input (electric) into total alternating current electric power with the possibility of operation both separately from each source and jointly. The hybrid machine-generator has a shaft, an armature with winding and a brush-commutator machine of direct-current machine, bearings, generator winding of alternating current. The armature shaft is immovably fixed on two sides in bearing shields of a stator. The main poles are positioned radially relative to each other, and are made of permanent magnets and are fixed from ends by bearing covers made of material with high magnetic resistance with bearings mounted on the shaft on both sides of the armature in the inner cavity of the stator with the necessary working air gaps between the armature and the magnetic core of the stator to rotate together with the brush holders and brushes relative to the armature and fixed on the stator of the magnetic circuit with the generator winding of the alternating current. The brush holders are fixed in the bearing cover considering the fact, that their axis is perpendicular to the axis of the main poles and shifted by the angle value of the physical neutral in the rotation direction of the main poles. The armature winding is connected to direct current source through the brush-collector unit. The contact rings are located on the outer side of bearing cover. The brushes are fixed with brush holders on the inner bore of the stator. There is a device excluding flow reverse direction current to direct current source. Simultaneously, an overrunning clutch is fixed on the bearing cover transmitting torque from wind turbine through the bearing cover to the main poles. The polarity of the connection of the direct current source is adjusted so that the rotational moments generated by the wind turbine and the main poles from the armature winding coincide in the direction.

EFFECT: increase of number, uniformity of electric energy supply, increase of reliability and stability of power system operation.
