AUTONOMOUS VALVE AC WIND GENERATOR Russian patent published in 2024 - IPC H02K19/38 H02K29/00 H02K1/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to AC electrical machines, and can be used, for example, for conversion of mechanical rotation energy into AC electrical energy. Autonomous rectifier wind generator of alternating current contains housing, in which subexciter, exciter and main generator are installed. Housing is installed with possibility of rotation by means of front and rear bearing assemblies. Axial magnetic conductor of subexciter armature with multiphase winding of subexciter armature and radial magnetic conductor of exciter inductor with single-phase exciter excitation winding are rigidly fixed on fixed axis by means of first disc. Radial magnetic conductor of the exciter armature with multiphase winding of the exciter armature is rigidly fixed on the inner side surface of the rear section of the housing coaxially with axial magnetic conductor, subexciter armature and radial magnetic conductor, exciter inductor, and their common axis of symmetry is axis of symmetry of fixed axis. Main generator inductor magnetic core with the main generator single-phase excitation winding is rigidly fixed on the housing middle section side surface inner side, magnetic conductor of the main generator armature with multiphase winding of the main generator armature is rigidly fixed on the fixed axis by means of the second disc and conical hub fixed against movement in axial direction by the retaining ring. On the front part of the fixed axle there is a hydraulic pump of the liquid cooling system fixed against movement in the axial direction by a collar and consisting of a housing with a cavity, eight pistons with cavities, springs, suction and pressure chambers, suction and delivery valves. First drain tubes are laid between the inner side of the side surface of the middle section of the housing and the magnetic core of the inductor of the main generator. Second drain tubes are laid between inner side of side surface of rear section of housing and radial magnetic conductor of exciter armature. Front part of each pressure chamber is connected to its first nozzle, and rear part of each pressure chamber is connected through its axial pipeline, Its first tee with its second nozzle and one end of its radial pipeline, which by the other end is connected by means of its second tee with its third and fourth nozzles.

EFFECT: increased reliability of generator by reducing probability of generator overheating due to facilitation of thermal mode of operation of its elements, as well as providing autonomy of its drive due to installation on the housing of blades to create torque.
