Turbogenerator Rotor & Exciter Windings
NEC is experienced with the manufacture of turbogenerator rotor windings: copper or aluminum; directly or indirectly cooled.
At our Columbus Rotating Equipment Service Center, we have made a significant investment in design, equipment and process development for our turbogenerator rotor winding manufacturing line. This includes the achievement of ISO 9001:2008 certification for our quality management systems. NEC manufactures windings with either style of end winding corners — square or edge-bent as shown above. Typically, old windings are replaced with new ones of similar design. All brazed joints, whether in the corners or in the arch, are UT tested to prove their durability.
- New or refurbished windings
- Copper or aluminum
- Direct or indirect cooling
- Square or edge-bent end turn corners
Refurbished Rotor Windings
Many successful rotor rewinds are accomplished by refurbishing the existing copper or aluminum conductors. Conductors are cleaned, polished, inspected and tested, and if found suitable, repaired, straightened and re-arched. Should an existing winding prove unsuitable for refurbishment, NEC's Rotating Equipment Service Center can design and manufacture new windings of any type. This includes both solid and ventilated conductors, as well as those with brazed or edge-bent corners. MORE about turbogenerator rotor rewinds.
NEC manufactures replacement armature coils for rotating exciters, leads and other electrical parts. Whether a complete refurbishment, including rewind, as shown in the picture above, or a maintenance overhaul and cleaning, NEC's goal is to get your machine back in operation expeditiously.
