These motors set a benchmark for the industry,
offering more watts per kilogram than has ever
been achieved before with rib cooled motors.
High power density means that for a given output
you can often use a motor one frame size smaller
than with conventional products. This helps to
save space and enables more compact
installations.
NXR motors have a rugged cast iron frame. They
are rib cooled motors with IC411 cooling and IP55
protection as standard. The motors are also
available with IC416 cooling and optional IP66
protection. Their IP66 protection has been
verified by a leading independent testing
organization.
NXR motors cover the output range up to
1,800 kW, and they are available in shaft heights
from 315 to 500 mm. The motors can be mounted
horizontally (vertical mounting available for frame
sizes 450 and 500). For NXR motors this catalog
shows the technical data at 50 Hz and 60 Hz, and
for synchronous speed from 500 to 3600 rpm.

High-voltage rib cooling motor NXR series and AXR series
NXR series and AXR series have the characteristics of compact model, high power density, high reliability, low loss and easy maintenance. Based on the successful experience of high-performance rib-cooling motor HXR series, a new-generation high-voltage rib-cooling motor is developed.
These rib-cooled motors for a wide range of applications provide high power density, they are easy to set up and easy to maintain. There is also a version that can be used with VSD. The motor controlled by the inverter means that it has a higher
Efficiency and more precise process control.
ABB rib cooling motors have general-purpose N series (NXR) and customized A series (AXR).
The general-purpose N series motors are based on standardized design, have high cost performance and short delivery cycle, provide customers with safe, reliable and efficient operation, and improve productivity. They are specially designed for applications that do not require highly customized applications.
