General Purpose TEFC motors are ideal
for both indoor and outdoor
applications and in operating
atmospheres that contain moisture,
dust and grit. These industry
workhorses are ideal for use in material
handling, pump, fan, compressor and
other industrial applications.

Features for Long Life
Frame & End Shields – Cast iron
construction (aluminum endshields
143T–256T frames) for exceptional
structural integrity with condensation
drain holes (143T–256T frames) or
condensation T-drains (284T–449T
frames). 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 air flow, reduces noise
and provides dependable cooling.
Polycarbonate fan covers are provided
on 143T up to 365T frames, and cast
iron for frames 404T and larger.

Bearings – Greaseable, oversized single
shielded with cast iron inner caps
(444T–449T frames), pipe plugs on both
the inlet and relief ports (143T–256T
frames). Alemite grease fittings on the
inlets and pipe plugs on the relief ports
(284T–449T frames) for ease of routine
maintenance. For added bearing
protection, 284T–449T frames are
equipped with 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 – Larger than
industry standards, diagonally-split,
gasketed and rotatable in 90°
increments for quick and easy
connections. Leads are non-wicking and
are clearly and permanently marked.
Aluminum construction for frames 143T
to 256T, steel for frames 284T to 405T
and cast iron for 444T frames and

Corrosion Resistance – Cast iron
construction, zinc-plated hardware,
epoxy enamel paint and aluminum
nameplate resist rust and corrosion.

Modifiable – All Siemens motors are
available with a wide variety of
modifications to meet your specific
motor needs.
