METHOD AND DEVICE FOR STATOR AND ROTOR WINDING MANUFACTURING, AND RESPECTIVELY PRODUCED STATOR AND ROTOR WINDING Russian patent published in 2008 - IPC H02K15/04 H02K3/12 

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of electric engineering and concerns execution particularities of coil windings for stators or rotors of electric machines with inside-open slots. Substance of invention consists in manufacturing of coil winding for stators or rotors where each coil turn with corresponding jumper wire (14) lays in two stator or rotor slots respectively and both jumper wires (14) are connected by frontal part (16) of winding protruding out of stator or rotor butt-end surface. At that simultaneously several coils are made by means of n parallel wires (10) winding on rotating pattern. To obtain smaller frontal winding parts, the jumper (14) and the frontal part (16) is alternatively created of each of parallel wires (10) on pattern (20) in the first working stage A. After that in working stage B, created jumpers (14) and wire guide are shifted together with one of the ends of these frontal parts (16) by means of axial moving of pattern (20). After multiple repetitions of working stages A and B, jumpers (14) are created for the last n stator slots. After that winding is removed from the pattern, flat-squeesed, put into coil receiver in the form of strip plate, then shift to open in radial direction slots of transfer tool and squeese out of them in radial direction outside into stator or rotor slots. Also device is suggested for manufacturing of stator or rotor with these windings.

EFFECT: providing of narrow in radial direction structure of winding frontal parts for certain cross-sections of wire in stator or rotor slot cross-section irrespective to winding insertion into rotor or stator method.
