Induction Brazing System for Short-Circuit Rings
ENRX short-circuit ring brazing systems utilize unique coil technology that delivers rapid, accurate and localized heating with minimal heat input. This minimizes thermal stress on shafts and prevents excessive heat transfer into laminations—common issues with flame brazing. Induction brazing provides precisely controlled temperatures, reducing the risks of oxidation, copper overheating, grain growth and ovality, thus eliminating post-process rebalancing of squirrel-cage rotors. Systems support both one-shot brazing for small/medium rings (up to ~1,500 mm OD) and segment brazing for large rings. Induction is clean, quiet, flame-free and ideal for automated and high-volume rotor production.
