DIRECT CURRENT WIND ALTERNATOR Russian patent published in 2020 - IPC H02K21/24 H02K9/02 F03D1/06 

FIELD: electrical engineering.

SUBSTANCE: direct current wind alternator contains stator with armature magnetic conductor and constant-magnet rotor made in the form of truncated cone. Stator base is made in form of fixed platform rigidly fixed on carrier rod, and the side surface of the stator is formed by the outer side of the armature magnetic conductor with slots, into which the three-phase armature winding is connected, which is connected to the three-phase full-wave rectifier rigidly fixed on the fixed platform. Rotor side surface is provided with curved blades. Front part of the rotor is provided with a fairing and ventilation holes located around the fairing along the circumference with the center on the axis of symmetry of the rotor. In front part of magnetic conductor of armature around front bearing unit there are ventilation holes, which axis of symmetry is parallel to axis of symmetry of rotor. Fixed platform is made in the form of truncated cone with ventilation holes located along circumference with center on rotor axis of symmetry and radius equal to four fifths of inner radius of base of armature magnetic conductor.

EFFECT: improved cooling.
