Abstract
A device is provided for producing a distributed wave winding. To improve the currently used method for producing a distributed wave winding the device provides for a relative indexing to be carried out between a template and a coil receiver after a first concentric coil group has been transferred from the template to the coil receiver. After this indexing, a further concentric coil group of the same phase, with a connection to the first coil group, is wound on the template and transferred to the coil receiver. The template and coil receiver rotate synchronously during the winding of the further coil group.
Claims5
A device for producing a distributed wave winding for electric motors or generators, said wave winding having a cross section and said device comprising:
- a fixed wire guide nozzle;
- a template rotatable relative to the fixed wire guide nozzle, the template having a cross section corresponding to the cross section of the wave winding so that, during rotation of the template, a coil wire is wound onto the template, turn by turn, into a wave form so as to form a first coil group of one phase;
- a coil receiver axially aligned with, and rotatable in synchronism with, the template;
- ejector means for transferring coil groups wound on the template to the coil receiver;
- and
- indexing means for providing relative indexing between the template and the coil receiver such that, after said relative indexing, a further coil group of said one phase, wound on the template with an interconnection to the first coil group, is in a position so as to be transferable to the coil receiver.
