Motor Data
For Table 17
* Optional variable speed switch is available.
** These motors have automatic thermal over-
load protection or impedance protection.
*** These motors are 230/460 volts only.
† Models 336 through 720 are not available for
either Totally Enclosed or Explosion Proof
with Overload 115/1/60 motor types.
Motor Data: S Models
ƽCAUTION
Voltage Selections
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.
Also refer to Maintenance section for
additional motor data.

Note: All motors are constant
speed and operate at top
speed as indicated in motor
data. Models 18 through 108,
including A08, A18, A25 and
A36 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 infinitely
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: 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: 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: Stated AMP draw is Full Load
Amp (FLA). AMP draw varies
by motor manufacturer ± 0.2
AMPS. Verify FLA per unit
motor data plate.
