Arrangement for manufacturing a heat winding cap

1. An arrangement for manufacturing a head winding cap of an electric machine having two spaced-apart winding arms and a clip connecting the winding arms together, the arrangement comprising a container that accommodates a moulding compound therein, the container configured for attachment to the two winding arms adjacent to the clip and encloses the winding arms, the container defining a cavity surrounded by side walls, the cavity containing the moulding compound and projecting perpendicular to the winding arms when attached, the arrangement further comprising a cap mold that fits over the clip and the winding arms, the cap mold having a bottom that extends into the moulding compound in the cavity, the side walls of the cavity defining a perimeter wall that surrounds the bottom of the cap mold, and the cavity creating a tight inclusion for the moulding compound, whereas the cap mold is filled with a dielectric compound.

2. The arrangement according to claim 1 , wherein the container is designed from two parts to be connectable when attached to the winding arms.

3. The arrangement according to claim 1 , wherein the container has a rectangular geometry.

4. The arrangement according to claim 1 , further comprising a removable silicon, a modelling clay, or a foam at the intersection of the winding arms and the container to support the tightness of the container.

5. The arrangement according to claim 1 , further comprising wires or a wrapping for securing the container that contains the moulding compound to the clip.
