MOTOR DATA
NOTE 1: All motors are constant speed and
operate at top speed as indicated in motor data.
Models 18 through 108, including 108A, 118A,
125A and 136A can be run at reduced speed
with addition of optional variable speed switch.
This switch is factory-calibrated for low and high
speed ratings, with intermediate speeds infi nitely
controllable. Models 120 through 360 operate at
constant speed as indicated in motor data. All 1/4
H.P. motors are P.S.C.
NOTE 2: Motors under 1/3 H.P. are totally
enclosed, frame mounted, 115/1/60 with thermal
overload protection and permanently lubricated
sleeve bearings with optional speed controller
available. 1/3 H.P. (115/1/60) motors are open
frame constant speed with thermal over-load
protection and ball bearings. 1/3 H.P. (230V) and
1/2 H.P. (230V) motors are open frame constant
speed with thermal overload protection and ball
bearings.
NOTE 3: 1/3 and 1/2 H.P. motors are available
as 230V single and 3 phase in open frame
and explosion-proof housings, all available
as options. 1/3 and 1/2 H.P. motors operate at
single speed only.
NOTE 4: Stated AMP draw is Full Load Amp
(FLA). AMP draw varies by motor manufacturer
± 0.2 AMPS. Verify FLA per unit motor data plate.
Select appropriate AMP,
MCA, and MOP for the multiple voltage
motors. For example , the AMP, MCA,
and MOP for Models 360 with a 460 volt
Totally Enclosed motor is 1.3, 1.6 and 2.9
respectively.
NOTICE: Also refer to Maintenance section for
additional motor data.
