ABB’s latest generation of multipurpose rib cooled motors offer high power density, easy configurability and built-in serviceability. The motors are based on the successful, high performance rib cooled motor range, type HXR. They incorporate experience ABB has gained over more than 100 years of manufacturing electric motors.
ABB’s high voltage rib cooled motors are available as N-series general purpose motors (type NXR) and A-series engineered motors (type AXR). N-series general purpose motors combine cost efficient standardized designs and short lead times with safety, productivity, energy efficiency and reliability. They are targeted at applications where a highly customized motor is not needed. A-series engineered motors are highly customized, fine-tuned to the customer’s precise needs, and offer a high degree of engineering flexibility.
Versions are available for both direct-on-line (DOL) and variable speed drive (VSD) operation.
Key features and benefits[edit | edit source]
• High efficiency for reduced cost of running
• High power density for more watts per kilogram than ever before with rib cooled designs
