NXR and AXR motors provide a unique combination of small size, high power density, high reliability, low losses and easy maintenance. They are based on the successful, high-performance rib cooled motor range, type HXR.

These multipurpose rib cooled motors offer high power density, easy configurability, and built-in serviceability. Versions specifically designed for use with variable speed drives are also available. VSD control generally means even higher efficiency and precise process control in both quadratic and constant torque applications.

ABB’s 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.

The pre-engineered N-series complements ABB’s A-series of engineered motors, which are highly customized, fine-tuned to the customer’s precise needs, and offer a high degree of engineering flexibility.
