Abstract

The disclosure relates to a method for producing a winding of a winding carrier of an electric machine. The method includes providing a laminated core. The laminated core has an axis and a first slot for accommodating a first winding segment for producing the winding. The first slot extends in the direction of the axis. The first slot is arranged on a first circle as viewed in the direction of the axis, through the circle center point of which first circle the axis extends. The method includes: arranging the first winding segment in the first slot, where a first region of the first slot protrudes from the laminated core; and bending the first region by applying a first force acting in the direction of the axis and by applying a first force acting tangentially to the first circle onto the first region in a first direction tangentially to the first circle.

First claim

The invention claimed is:

1. A method for producing a winding of a winding carrier of an electric machine, the method comprising:
providing a laminated sheet package, the laminated sheet package includes:
an axis,
at least one first slot, extending in a direction of the axis, for receiving at least one first winding segment for producing the winding, wherein the at least one first slot, when viewed in the direction of the axis, is disposed on a first circle, the axis running through a circle center of the first circle;

disposing the at least one first winding segment in the at least one first slot, wherein a first region of the at least one first winding segment protrudes from the laminated sheet package; and
bending the first region by exerting a first force, acting in the direction of the axis, and a frictional force, acting tangentially to the first circle, on the first region in a first direction tangential to the first circle;
wherein bending of the first region is performed by way of a first pressure unit having a first contact face that is configured as a doughnut-shaped face having a linear structure or a non-structured rough surface extending away from the axis, the first contact face contacting an exposed end portion of the first region creating the frictional force that pulls the exposed end portion in the first direction tangential to the first circle.

2. The method of claim 1 , wherein bending the first region includes moving a first contact face toward the laminated sheet package and rotating the first contact face about the axis, wherein the first contact face when moved and rotated physically contacts the first region, and exerts on the first region the first force, acting in the direction of the axis, and the first force, acting tangentially to the first circle.

3. The method of claim 1 , wherein providing the laminated sheet package furthermore provides that the laminated sheet package is provided having at least one second slot, extending in the direction of the axis, for receiving at least one second winding segment for producing the winding, wherein the at least one second slot, when viewed in the direction of the axis, is disposed on a second circle, the axis running through the circle center of the second circle;
wherein the method further comprises:
disposing the at least one second winding segment in the at least one second slot, wherein a second region of the at least one second winding segment protrudes from the laminated sheet package; and
bending the second region by exerting a second force, acting in the direction of the axis, and a second force, acting tangentially to the second circle, on the second region, in a second direction, tangential to the second circle and substantially facing the at least one first winding segment.

4. The method of claim 3 , wherein bending includes moving a second contact face toward the laminated sheet package and rotating the second contact face about the axis, wherein the second contact face when moved and rotated physically contacts the second region, and exerts on the second region the second force, acting in the direction of the axis, and the second force, acting tangentially to the first circle.

5. The method of claim 3 , wherein bending of the first region, and bending of the second region take place so as to be substantially simultaneous.

6. The method of claim 3 , wherein bending of the first region, and bending of the second region take place so as to be mutually temporally offset by a predefined temporal spacing.

7. The method of claim 3 , wherein the method furthermore comprises:
connecting in electrical terms a first exposed end portion of the first region to a second exposed end portion of the second region.

8. The method of claim 7 , wherein the method furthermore comprises:
positioning of an electrically conducting connection element between the first exposed end portion and the second exposed end portion; and
connecting in electrically conducting and physical terms the electrically conducting connection element to the first exposed end portion and to the second exposed end portion.
