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
