Improved operating efficiencies
through use of
state-of-the-art lamination designs and lamination
steels. Die cast rotor is heat-shrunk to shaft.
Endshield stiffening ribs
provide
increased rigidity to meet demands
of high load applications. Cast iron
bearing inserts for longer life and
quieter operation.
C face models
feature bearing lock to
withstand 1000+ lb axial loads. C face
endshield designed to handle five times
motor weight in overhung load.
EPACT efficiencies and IRIS
™
(Inverter Rated Insulation
System) are standard on three phase models. Protects
against inverter-generated voltage spikes, efficiency
verified by independent laboratory.
Endshield design
places the bearing load directly over
the frame rabbet for excellent radial stiffness and shaft
load capabilities. Double shielded bearings (each end)
with Shell Dolium R Lubricant.
Cooler running temperatures
are achieved
by using air guides on the endshield to
straighten airflow over the frame for improved
heat dissipation and longer insulation life.
Full fact metal nameplate
has connection data,
amperage and efficiencies.
“Full-opening conduit box”
cover
makes for easier access to connections.
Standard steel box features one 1-3/8”
and three 1-1/8” knockouts.
Starting switch and field proven
centrifugal device
(single phase
only) for maximum reliability and
performance, even in applications
requiring frequent starts.
Look Inside the LEESON 182-4T Frame Motor
Fan guard, fan and endshield
work
together to provide frame-hugging
airflow for maximum cooling and over-
load capacity. Vents in fan guard meet
UL 1/4” articulated probe standard for
safe operation.
Large conduit box
(steel) and optional box
(aluminum) are interchangeable and use the
same mounting pattern. Cover lip design
reduces contaminate infiltration and enhances
dust-tight gasket seal. Box volume exceeds
new NEC requirements.
Large capacitor housing
(single phase) with large MFD
capacitors, one molded gasket/joint and simplified wiring.
Double-strength lifting lug
can
support ten times the motor weight.
Internal fan
of high temperature, glass-
filled nylon remains secure–even during
the highest temperatures–and provides
improved airflow. Reduces “hot spots”
and increases insulation life.
Heavy-gauge base
is extra-strong
and provides reduced flexing and
improved structural stiffness.
