A method and apparatus for winding coils is drawn axially parent in grooves of the stator - or rotor sheet packets for electric machines

摘要

For the method of winding coils parent is drawn axially into the grooves of the stator - or rotor sheet packets is a retracting mechanism with annularly arranged, parallel, axially movable maintenance of lamellae (16) and a central, axially movable maintenance of a star (20) is used. It pushes the inner peripheral areas of the maintenance of between the lamellae (16) suspended coil turns (10) through the bore of the laminated core (12) through. Thus the first, which are pushed through the coil turns do not impede the complete pushing the following, it is provided that during an insertion process, in a specific intermediate phase the already by means of the rear end face of the laminated core (12) preceding winding heads (66) of a part of the coil windings (10 '') are displaced radially outward, and then the remaining coil turns (10 ") completely through the bore of the laminated core (12) are pushed.
