Motors - Sealed
The W21TM Severe Duty
High Efficiency motors are
designed to meet or exceed all
EPAct requirements for
energy efficiency as defined
by the DOE. The efficiency
values are certified according
to the DOE's regulations
(Certificate of Compliance
number CC029A).
W21TM motors meet the most
demanding severe duty
application requirements.
These TEFC motors are all
cast iron construction, with
enclosures rated IP55 to
handle wet and dirty
environments. They are
painted with a special system,
using synthetic enamel alkyd
resin paints, which exceed the
ASTM B117 standard for salt
spray test. The W21TM line is
rated for 1.25 Service Factor
up to 100HP and meet Design
B (up to 100HP) and Design
C (from 15HP up to 100HP)
torque requirements. This line
is rated for dual frequency and
dual voltage (with reduced
service factor) up to 60 HP.
And the entire line is certified
Inverter Rated for use with a
VFD. This rating meets or
exceeds MG1 Part 31 NEMA
Specifications.

Encoders - Sealed
For applications that require encoder feedback
we offer a sealed unit that can be purchased
separately or added to any motor.
For elevator speeds over 150 FPM we
recommend utilizing encoder feed back with a
VVVF drive. We also recommend encoder feed
back when car capacities are much larger than
the normal elevator.
