MULTITURN NON-CONTACT MONOPOLAR DIRECT CURRENT GENERATOR Russian patent published in 2009 - IPC H02K21/20 

FIELD: electrics.

SUBSTANCE: invention concerns electric equipment and electric DC machines. Multiturn non-contact monopolar direct current generator includes armature and inductor. Armature is immobile and consists of toroidal multiturn winding with hollow core featuring rectangular cross-section and ferromagnetic internal wall with peripheral groove for beads. Two side walls and open external wall with peripheral groove are made of non-magnetic materials. Inductor mounted in armature cavity is mobile and is consists of several permanent rod magnets with south poles adjoining internal ferromagnetic ring and north poles adjoining external non-magnetic ring with grooves. Permanent rod magnets of inductor can move freely on beads of internal and external armature core walls by friction link of external inductor rim ring to guided and guiding gears of reducer in armature body hole area at external armature side.

EFFECT: simplified construction, improved reliability and electromechanical properties.
