Method and device for producing rotors and stators including the production of connection wires

Abstract

A method used for producing rotors and stators of electric motors, including the production of connection wires, and comprises the following steps: Winding the coil windings (12), which comprise a plurality of individual wires (14), on a wire winder (28) to which the individual wires (14) are fed from a wire supply unit (16) via a wire guide 18, 20, 22), Depositing the coil windings (12) in a draw-in tool (36), Drawing the coil windings (12) into grooves of a stator (84) or rotor body, Combining the individual wires (14) in phases by means of slide-on tubes (52) to produce the connection wires of the stator or rotor in question. In order to be able to automate the production of the connection ends, which was previously carried out manually, it is proposed that the individual wires (14) of each coil winding (12) are fastened to each other in the region of the wire guide (18, 20, 22) in order to form winding ends (46) and winding beginnings (32), after the winding and before or during the depositing, the winding ends (46) and winding beginnings (32) of each coil winding (12) are fastened in first position holders (42, 44) arranged in certain positions with respect to the draw-in tool, and during the drawing of the coil windings (12) into the stator or rotor, the winding ends (46) and winding beginnings (32) are transferred from the first position holders (42, 44) into second position holders (90, 92) arranged in certain positions with respect to the stator body (84) or rotor body. The present invention also relates to a device for carrying out the aforesaid method.
