Claims12
A slot wedge for a slot in a stator of a dynamo-electric machine;
- wherein the slot wedge is formed as a longitudinally extending strip made from insulating material;
- and wherein a punched portion, extending in a same longitudinal direction as sides of the slot wedge and protruding into an interior space formed between the sides of the slot wedge, is arranged in the longitudinally extending strip at a bottom of the slot wedge.
A tool for installing a winding in a slot and a slot wedge closing off the slot, the tool comprising:
- a slot template which is configured on a top side to receive the winding to be installed and is configured on a bottom side via a receiving surface to receive the slot wedge;
- wherein the slot wedge is formed as a longitudinally extending strip made from insulating material in which a punched portion is arranged;
- wherein the receiving surface includes a cut-out and the punched portion is arranged above the cut-out such that a hook arranged on the bottom side immerses into the punched portion and provides an engagement for transporting the slot wedge along the slot;
- and
- wherein the slot is simultaneously closed off by the slot wedge when introducing the winding.

A method for simultaneously installing a winding in a slot and a slot wedge closing off the slot, the method comprising:
- arranging a winding to be installed on a top side of a slot template via the slot template and arranging the slot wedge on a bottom side of the slot template on a receiving surface via the slot template, the slot wedge being formed as a longitudinally extending strip made from insulating material;
- arranging a punched portion in the longitudinally extending strip made from the insulating material;
- wherein the receiving surface includes a cut-out, and the punched portion is arranged above the cut-out such that a hook arranged on the bottom side immerses into the punched portion with a forward movement to provide an engagement for transporting the slot wedge along the slot;
- and
- wherein the slot is closed off by simultaneously transporting the slot wedge when introducing the winding in the slot.
