DIRECT CURRENT VALVE WIND GENERATOR Russian patent published in 2017 - IPC H02K7/18 F03D9/00 

FIELD: electricity.

SUBSTANCE: direct current valve wind generator comprises: a stator with an armature magnet core, which slots a three-phase winding is laid and connected to a three-phase double-wave rectifier, and a rotor with permanent inductor magnets. The stator, the armature magnet core and the rotor are made in the form of a truncated cone. The stator base is made in the form of a fixed platform rigidly secured on a rod-holder, and the side surface of the stator is formed by outer side of the armature magnet core with grooves in which the three-phase winding is laid. One end side of the armature magnet core is rigidly attached to the secured platform, and on the opposite end face of the armature magnet core there is a front bearing assembly. The rotor side surface is provided with blades of curved shape, the front portion of the rotor is provided with a fairing and ventilation openings located around the fairing along a circumference centred on the axis of the rotor symmetry, and permanent magnets of the inductor are rigidly fixed on the rotor inner surface. The rotor is rididly mounted on a rotating axle mounted in the front and rear bearing assemblies, the rear bearing assembly is mounted in a fixed platform and secured against movement in the axial direction the thrust washer, and the three-phase double-wave rectifier is rigidly mounted on the fixed platform.

EFFECT: reduced axial and diametric dimensions of the wind generator, reduced energy losses in converting when mechanical energy into electrical energy of direct current, increased sensitivity of the wind generator to the velocity of incoming air flow, higher structure rigidity.
