INVERTED ELECTROMAGNETIC WIND GENERATOR Russian patent published in 2008 - IPC F03D1/06 F03D3/06 H02K21/22 

FIELD: electricity.

SUBSTANCE: inverted electromagnetic wind generator consists of hollow shaft, lead-out, single-layer three-phase winding, two end shields and metal drum fixed between end shields by means of outer flanges. Prismatic magnets are installed on inner surface of metal drum at equal distance. Prismatic magnets with longitudinal axis, which is parallel to axis of rotation, have radial degree of magnetisation N-S, the said prismatic magnets being fixed from both sides with retaining rings. Groove-free stator is placed inside metal drum and consists of cylindrical hub with central hole the aforesaid cylindrical hub being installed on hollow shaft in co-axial alignment. Cylindrical bundle is reeled on hub as metal strip installed edgewise. Single-layer three-phase winding is put above bundle. Winding ends are parallel to axis of rotation of wind generator. Guiding cylindrical bushings with circular hollows and circular guiding sections are installed in circumferential direction of groove-free stator at end surfaces. Lead-out is disposed inside hollow shaft to connect single-layer three-phase winding with lead-outs. Shaft is attached to end shield from the opposite side of hollow shaft outlet in its central part by means of flange connection.

EFFECT: electric energy supply to power grid at low rotation frequencies; high reliability and easiness in manufacture process.
