ENERGY-EFFICIENT ELECTRICAL MACHINE Russian patent published in 2014 - IPC H02K17/00 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering, in particular, to electric machines. The electric machine comprises additional front wires by which active wires are connected in grooves where wires of winding phase starts are placed with active wires in grooves where wires of winding ends of the same phase are placed; active wires placed in the same groove are interconnected by front wires with active wires of the same phase place in another groove in reverse sequence: in direction of phase alternation the first wire in one groove is connected to the last wire of another grove, the second wire in one groove is connected to the next to last wire in another groove and the last wire in one groove is connected to the first wire in another groove. Additional front wires are placed over butt end of the core toothed area with the part of grooves where a winding layer is placed.

EFFECT: reduction of weight, saving of material consumption and improvement of efficiency factor.
