2015 Low Voltage AC Motors Selection and Pricing Guide
SD100 IEEE841
severe duty/IEEE 841 TEFC motors are
available in two configurations which exceed NEMA Premium®
efficiency with our exclusive, leading-edge, die cast copper
rotor design (143T-256T) or meet NEMA Premium® efficiency
with our die cast aluminum rotor design (143T-S449).
They also exceed IEEE Std 841
TM
-2009 standards for high
performance, rugged construction and long service life, for
the most demanding industrial applications. They are ideal for
use in chemical processing, mining, foundry, pulp and paper,
waste management and petro/chemical applications.
