  • Bearings
    • Bearing RTDs for temperature monitoring
    • Insulated non-drive end bearings to reduce bearing currents
    • Anti-friction on 1500 hp (optional)
  • Rotors
    • Designed for minimal vibration
    • Dynamic balancing at full operational speed
    • Fabricated copper squirrel cages
    • Forged, keyless shaft
    • AISI 4140/DIN42CrMo4 shaft
  • Stators
    • Radial air ducts ensure uniform and efficient cooling
    • Vacuum pressure impregnated with specially formulated epoxy resin
    • 2X RTDS per Phase
    • Space heater
    • Welded and machined stator core retains its rigidity throughout motor life to ensure a sealed and homogeneous insulation system that results in high dielectric strength, excellent heat transfer and the elimination of hazardous internal partial discharges
