STABILIZED AXIAL-CONICAL 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-conical DC valve wind generator comprises stator, base of which is made in form of fixed platform, rigidly fixed on carrier rod, and a rotor, which external side surface is made with curved blades. Front part of the rotor is provided with a fairing and inlet ventilation holes located around the fairing along the circumference with the center on the axis of symmetry of the rotor. Rotor is fixed on the axis. On the fixed platform the outlet full-wave rectifier is rigidly fixed. Axle is fixed with collar in middle part and is pressed into hole made in center of fixed platform, where the axial magnetic conductor of the main generator armature with the multi-phase winding is rigidly fixed and the voltage regulator, the input of which is connected to the output of the multiphase output rectifier. On fixed axis there fixed is magnetic conductor of exciter in the form of truncated cone, in slots of which there laid is single-phase winding of its excitation connected to output of voltage regulator according to multi-phase winding of generator armature. In front part of inner cavity of rotor is rigidly fixed magnetic conductor of exciter in form of truncated cone, in slots of which its multiphase winding is laid. In rear part of rotor inner cavity there rigidly fixed is axial magnetic conductor of generator inductor, in slots of which on the 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 located along circumference with center on axis of symmetry of rotor in close proximity to diodes of rectifier, and with boring in its central part, in which outer ring of rear bearing is installed, inner ring of which is installed with interference in middle part of fixed axis, at that, rear bearing is fixed against movement in axial direction by collar and bushing installed on axis made fixed, between rear bearing and exciter inductor magnetic conductor, made in form of truncated cone, and the fairing rear part is made with boring, in which outer ring of front bearing is laid, which inner ring is fixed with interference in front part of fixed axis.

EFFECT: minimization of difference between actual and specified values of output voltage, increase of structure rigidity, reduction of energy losses at conversion of mechanical energy into electric energy of direct current, reduction of coefficient of pulsations of rectified voltage.
