Continuous stator winding wound on bobbins
First Claim
1. A method for producing a stator winding of a stator, comprising:
- positioning an auxiliary element relative to the stator such as to align a central axis of the auxiliary element with a central axis of the stator;
arranging bobbins on the auxiliary element at a radial distance from a central axis of the auxiliary element and in uniformly spaced-apart relationship around the central axis of the auxiliary element, when viewed tangentially around the central axis of the auxiliary element;
arranging a circuit carrier on the auxiliary element radially inside the bobbins;
winding a conductor wire for each phase of the stator winding onto a corresponding one of the bobbins to form coils of the stator winding;
routing the conductor wire of each phase via the circuit carrier to another one of the bobbins of said phase and winding the conductor wire onto the other one of the bobbins; and
pivoting each of the bobbins with the coils about a pivot axis that extends tangentially to the central axis of the auxiliary element and the central axis of the stator in vicinity of the circuit carrier so as to respectively pivot up the bobbins onto radially outwardly protruding stator teeth of the stator from radially outside.

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.

11. A stator, comprising:
-
a plurality of stator teeth configured to protrude radially outward from a connecting structure that extends circumferentially around a central axis of the stator at a radial distance from the central axis; bobbins arranged on the stator teeth at a radial distance from the central axis of the stator and, viewed tangentially around the central axis of the stator, in a uniformly spaced-apart relationship around the central axis of the stator; a circuit carrier arranged at an axial end of the bobbins; and a conductor wire wound onto each of the bobbins such as to form a coil of a stator winding of the stator, wherein, for each phase, the conductor wire is routed via the circuit carrier from the bobbin to another one of the bobbins of the phase in an axially offset manner in the circuit carrier from phase to phase, and wherein the circuit carrier has one carrier section per phase, said carrier sections being stacked on top of one another, viewed in a direction of the central axis of the stator. - View Dependent Claims (12, 13, 14, 15)
