NXR 7100 Motors Offer Power-Dense Design
Description
Above NEMA (ANEMA) NXR 7100 motors offer more hp per pound than conventional TEFC (totally enclosed fan-cooled) motors but with a smaller frame size in some power ratings. This helps save space, up to 8 in. in overall length in some cases, which enables more compact installations for industrial applications. The NXR 7100 is Class I Div 2 capable, making it ideal for hazardous area locations.
The NXR motors offer improved cooling, a critical factor to extend the life of the motor. An internal cooling loop circulates air inside the motor, moving heat from the rotor to the frame, where an external fan blows air over the frame to remove the heat.
As the main terminal box and auxiliary box can be mounted in several positions, installation, and maintenance are easy. This also means fewer spares are needed, which saves money. The rigid frame increases stability so that the motor can meet NEMA vibration requirements.
NXR 7100 motors extend the power range of the existing NXR 5000 and NXR 5800 up to 1750 hp while offering the same great features. These motors are available with up to an IP56 rating, for protection against contaminants and dust ingress.
