Severe Duty High Efficient TEFC

RGZPSD – Horizontal, Foot Mounted


Severe Duty TEFC motors are ideal for
both indoor and outdoor applications
and in severe operating atmospheres.
These motors are ideal for use in
chemical processing, material handling,
pump, fan, compressor and other
industrial applications.

Features for Long Life

Frame & End Shields – Cast iron
construction for exceptional structural
integrity with condensation T-drains.
Lifting eyebolts are included for frames
213T to 449T.

Rotor – A unique offset rotor bar design
provides improved efficiency while
larger bars and end rings reduce
resistance for lower rotor losses. Each
die cast aluminum rotor assembly is
dynamically balanced for extended
bearing life, and includes a highstrength
carbon steel (C1045) shaft for
maximum rotor performance.

Stator/Windings – Manufactured with
premium electrical grade steel
laminations and copper electrical
magnet wire to lower losses for
improved efficiencies. A unique stator
core design lowers flux density while
increasing cooling capacity.

Insulation – Proprietary inverter-rated
NEMA Class F non-hygroscopic
insulation system with Class B
temperature rise, provides an extra
margin of thermal life. Varnish system
application ensures maximum wire
penetration to provide protection from
moisture, corrosion and electrical shock.
This insulation system is suitable for
operation with variable frequency

Cooling – A bi-directional, non-sparking
fan is locked and keyed to the shaft. Its
low-inertia design reduces windage
losses, improves airflow, reduces noise
and provides dependable cooling. Cast
iron fan covers are provided on all frame

Bearings – Greaseable, oversized single
shielded with cast iron inner caps
(404T–449T frames). Alemite grease
fittings on the inlets and pipe plugs on
the relief ports for ease of routine
maintenance. For added bearing
protection, 143T–256T frames have a
drive end shaft seal and 284T–449T
frames have a drive end shaft V-ring

Lubrication – A specially formulated,
high temperature tested, polyurea based
grease is used to provide more than four
times the lubrication life of other
polyurea greases.

Oversized Conduit Box – Cast iron
construction that is larger than industry
standards, diagonally-split, neoprene
gasketed and rotatable in 90°
increments for quick and easy
connections. Includes a ground lug and
non-wicking, clearly and permanently
marked leads.

Corrosion Resistance – Cast iron
construction, zinc-plated hardware,
epoxy enamel paint and stainless steel
nameplate resist rust and corrosion.
Modifiable – All Siemens motors are
available with a wide variety of
modifications to meet your specific
motor needs.
