Above NEMA AC motors

EP Editorial Staff | May 16, 2020

Above NEMA (ANEMA) NXR 7100 motors offer more horsepower per pound than conventional TEFC (totally enclosed fan cooled) motors but with a smaller frame size in some power ratings.

This helps save space, reportedly as much as 8-in. in overall length in some cases, allowing more compact installation. The motors are Class I Div 2 capable and offer improved cooling. 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.
