Heavy gauge steel mounting bases
simplify the
installation of motors and make the tensioning, maintenance
and replacement of belts a simple efficient task. Fabricated
from sheet or steel plate, then primed and finished in a gray
rust and corrosion resistant oven-baked finish. Gussets
and reinforcing channels on larger units and continuous
welding on all units give these bases strength and durability
for a long life. A single (215T frame and smaller) or double
(NEMA 254T frame and larger) zinc plated adjusting screw
is provided. Motor mounting bolts are included.
ADJUSTABLE MOTOR BASES—NEMA 48-447T FRAMES
Transition bases
compensate for the difference in mounting
dimensions and shaft height of a rigid base NEMA T frame
to the next higher NEMA U frame. This makes it possible,
for example, to replace a 10 HP NEMA 254U frame motor
with a 10 HP NEMA 215T frame motor without modifying the
basic installation. Made of the same high-quality materials
and construction as the adjustable motor bases above.
They are for horizontal mountings, shimming may be
needed for direct coupled loads. Thread size listed is
for mounting transition base to the “T” frame motor.
Dimensions listed are for one piece—two are supplied,
one for each side of the motor’s foot.
