METHOD, DEVICE AND TRANSFER TOOL FOR WINDING COILS AND DRAWING THEM INTO STATORS OF ELECTRICAL MACHINES

WIPO Patent Application WO1999054989

A3

The invention relates to a method for winding coils and drawing said coils into stators of electrical machines. According to said method the coil windings (14) are wound on a template (14), pushed onto rods (12) of a transfer tool (10) arranged in a circle, transferred by means of said tool onto lamellae (22, 24), also arranged in a circle, of a drawing-in tool (30) and then drawn into the grooves of a stator. To be able to simplify the tools the invention provides for the coil windings (14) in the transfer tool (10) to extend from the slots between the rods (12) in a substantially straight line radially inwards through the slots between the lamellae (22, 24) when the transfer tool (10) is positioned coaxially and parallel above the drawing-in tool (30). To draw-in the coils the stator is placed onto the drawing-in tool (30) in front of the free ends of the rods (12).
