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
- 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
