Standard Equipment

  • Bearing RTDs for temperature monitoring
  • Insulated non-drive end bearings to reduce bearing currents
  • Anti-friction on 1500 hp (optional)
  • Designed for minimal vibration
  • Dynamic balancing at full operational speed
  • Fabricated copper squirrel cages
  • Oversized, forged, keyless shaft
  • AISI 4140/DIN42CrMo4 shaft
  • 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
