Efficiently Braze Pole Coils with Automated Systems

Pole coils that are used in the synchronous generators of hydro power plants for instance, need to be brazed with high precision. An automatic brazing system from eldec integrated with eldec's Custom Line MFG 75 generator ensures efficient processes.

Precise Induction Brazing

Synchronous generators are the core of a number of power plants. They are used for electricity production. Pole coils, in turn, are a vital component found in all synchronous hydro generators. They are inserted or wound directly onto each pole.

Keeping this in mind, it is evident why the brazing of pole coils is a challenging process. The component has to be precisely placed and fixed in place prior to brazing. Finally, the brazing site is then pressed to stop protrusions around the brazing area.

Eldec’s induction experts have developed a brazing system for the manufacture of pole coils that performs the challenging brazing work completely automatically. eldec’s Custom Line MFG75 medium-frequency generator is used as the energy source. This advanced induction generator supplies the required power without any delay, allowing brazing to start immediately. As a result, users stand to benefit from a fast, precise application of heat – which eventually means unmatched brazing quality.
