6 AC Induction Motors
Coupled Drive
Motors will operate successfully mounted on the floor, wall or
ceiling, and with the shaft at any angle from horizontal to vertical.
Special mountings, duty or thrust demands may, however, require a
different bearing system.
Stub Shaft Installation Procedure
Screw-in Stub Shaft
1. Turn off and lockout power to the motor.
2. Remove in-line blower motor and cover assembly by removing
the hex head cap screws on the cover (if enclosure is TEAO-
Blower cooled).
Important: An extended blower cover is required when a feedback
device is installed. Contact Allen-Bradley for
assistance with an in-line blower.
3. Check the motor shaft center hole for chips, dirt, or other residue
and clean as required.
4. Obtain the stub shaft to be screwed into the motor shaft.
5. Apply an even coat of Loctite ® Number 271 (or equivalent) to the
stub shaft thread. Place stub shaft in motor shaft threaded hole
and hand tighten.
6. Using a spanner wrench on the motor shaft drive end (or alternate
means of locking motor shaft), torque the stub shaft to 27 N-m
(20 lb.-ft.).
7. Using a dial indicator with 0.0005 inch graduations, indicate the
stub shaft to within 0.002 inch T.I.R. When Inland tachometers
are used, the tachometer stub shafts must indicate to within 0.001
in. T.I.R.
8. Mount feedback device per manufacturer's instructions.
!
ATTENTION: Motor C-face is intended for mounting
auxiliary equipment such as pumps and gears. When
mounted horizontally, C-face motors should be supported
by the feet and not by the C-face. Installations requiring
horizontally mounted motor frames L280C and L440 must
be supported by the feet as well as C-face or D-flange.
Failure to observe these precautions can result in damaged
equipment and/or personal injury.
