STABILIZED DC AXIAL-RADIAL DIRECT-CURRENT VALVE WIND GENERATOR Russian patent published in 2019 - IPC H02K47/00 H02K7/18 F03D9/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, and can be used, for example, as a mechanical converter of mechanical energy of air flow (for example, incident airflow energy when used on mobile local objects, wind energy when used on fixed local objects) into direct current electric energy. Stabilized axial-radial direct-current valve wind generator comprises stator, base of which is made in form of fixed platform, rigidly fixed on carrier rod, and rotor, which external side surface is made with curved blades, and rotor front part is made with fairing and inlet ventilation holes located around fairing along circumference with center on axis of symmetry of rotor. Rotor is fixed on the axis. Three-phase full-wave rectifier is rigidly fixed on fixed platform. Axle is fixed, with collar in middle part, and is pressed into hole made in center of fixed platform, where rigidly fixed axial magnetic core armature of main generator with three-phase winding and voltage regulator, which input is connected to output of three-phase rectifier output. On the fixed axis there rigidly fixed is the exciter inductor radial magnetic conductor, in the slots of which there is a single-phase excitation winding of the exciting connected to the voltage regulator output according to the main generator three-phase winding. In front part of inner cavity of rotor there rigidly fixed is radial magnetic conductor of anchor of exciter, in slots of which there laid is multiphase winding of anchor of exciter, and in rear part of inner cavity of rotor there rigidly fixed is axial magnetic conductor of inductor of main generator, in slots of which on side of axial magnetic conductor of its anchor there laid is single-phase excitation winding connected to output of rectifier. Rotor is installed on axis made fixed by means of disc fixed in inner cavity of axial magnetic conductor of inductor, and made with outlet ventilation holes along circumference with center on axis of symmetry of rotor in close proximity to diodes of multiphase full-wave rectifier, and with boring in its central part, in which external ring of rear bearing is installed, inner ring of which is installed with interference in middle part of fixed axis. Rear bearing is fixed against movement in axial direction by collar and bushing installed on axis, made fixed, between rear bearing and radial magnetic conductor of exciter inductor. Rear part of fairing is made with boring, in which external ring of front bearing is laid, inner ring of which is fixed with interference in front part of axis made fixed.

EFFECT: expansion of operational capabilities with simultaneous increase of its reliability, simplification of manufacturing technology and increase of efficiency factor.
