2015 Low Voltage AC Motors Selection and Pricing Guide
SD661
severe duty/IEEE 841 TEFC motors are available in
NEMA Premium® efficiency with our die cast aluminum rotor
design (184T-365T). They also exceed IEEE Std 841TM-2009
standards for high performance, rugged construction and long
service life, for the most demanding industrial applications.
Also build in compliance with the requirements of API661
standard by incorporating roller bearings on frames 210-360
making them ideal for use for heavy belt driven heat
exchangers applications in petro/chemical applications.
NEMA Premium® is a certification mark of the National Electrical Manufacturers Association.
