Abstract

A heating system for brazing a stator bar to a clip including: a heating coil having a seat to receive the stator bar and clip; a heating mass adapted to fit into the seat of the coil, and an extendible press applying the mass to the stator bar or clip.

Claims

1. A heating system for brazing a stator bar to a clip comprising:

a heating coil having a seat to receive the stator bar and clip;

a heating mass adapted to fit into the seat of the coil, and

an extendible press applying the mass to the stator bar or clip.

2. The heating system in claim 1 wherein the heating coil includes a U-shaped section and the stator bar seats in the U-shaped section.

3. The heating system in claim 2 wherein the heating mass seats in the U-shaped section.

4. The heating system in claim 1 wherein the heating mass is conductive.

5. The heating system in claim 1 wherein the heating coil is at least one of a resistive coil and an inductive coil.

6. The heating system in claim 1 wherein the heating mass substantially fills an area defined by an entrance to the heating coil.

7. The heating system in claim 1 wherein the heating mass substantially fills an area defined by an entrance to the U-shaped section.

8. The heating system in claim 1 wherein the stator bar includes a stator bar end and a clip, and the clip further includes a cover fitting into a slot in the clip, and the method further comprises abutting the conductive mass against the cover and conducting heat from the mass to the cover.

9. The heating system in claim 1 wherein the heating coil is an induction or resistive heating coil.

10. The heating system in claim 1 wherein the extendible press is a ram and the ram abuts against the heating mass.

11. The heating system in claim 10 wherein the heating mass is attached to an extendible ram of the press and the mass is applied to the assembly.

12. The heating system in claim 1 wherein the heating coil is stationary and the stator bar is moved into the seated position.
