Abstract

In a method for producing a stator winding of a stator, an auxiliary element is positioned with its central axis in alignment with a central axis of the stator. Bobbins are arranged on the auxiliary element in uniformly spaced-apart relationship around the central axis of the auxiliary element, and a circuit carrier is arranged on the auxiliary element radially inside the bobbins. Coils are formed by winding a conductor wire for each phase of the stator winding onto a corresponding one of the bobbins and routed via the circuit carrier to another one of the bobbins of this phase and wound thereon. Each of the bobbins is pivoted with the coils about a pivot so as to enable the bobbins to pivot up onto radially outwardly protruding stator teeth of the stator from radially outside.
