High voltage rib cooled motors, type NXR and AXR, technical data

Benefits:

  • High power density for more watts per kilogram than ever before with rib cooled designs
  • High efficiency for reduced cost of running
  • Rigid, weight-optimized frame is engineered to minimize vibration
  • Built-in serviceability features to reduce downtime and cost of not running
  • Compact size for smaller overall installations
  • Interchangeable terminal boxes reduce need for spare motors
  • Versions optimized for VSD operation can deliver even higher efficiency
  • Designed for easy deployment of ABB condition monitoring systems
  • Verified protection level up to IP66 allows installations in demanding environments
