Equipment

Standard Equipment

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
• Oversized, 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
