Abstract

A device for winding coils for electric motors is improved by simplifying the gripping element that holds and grips the wires. The device includes a winding template, a winding nozzle, a receiver for the coils, and the gripping element. In previous devices, the gripping element is moved in three dimensions, requiring a relatively complex system to control its motion. In the present invention, the gripping element is moved in two dimensions only which simplifies its construction and control, but without sacrificing any of its functions.
