Description

Featuring compact models, high power density, high reliability, low losses and easy maintenance, the NXR Series and AXR Series are a new generation of high-voltage tendon-cooled motors based on the success of the high-performance tendon-cooled motor HXR Series.

These tendon-cooled motors for a wide range of applications offer high power density, they are easy to set up and easy to maintain. Versions are also available for use with VSDs. The inverter-controlled motors mean higher efficiency and more precise process control, both for quadratic and constant torque load applications.

ABB tendon-cooled motors are available in the general-purpose N series (NXR) and the customized A series (AXR).

The general-purpose N-Series motors are based on a standardized design with high cost performance and short lead times, providing customers with safe, reliable, efficient operation and increased productivity, designed for applications that do not require a high degree of customization.

The Universal N Series complements the Customized A Series, which offers a high degree of design flexibility specifically for markets that require a high degree of customization based on precise customer needs.
