7. ALIGNMENT
If the motor is directly coupled to the load, alignment is very
important. The type of coupling device determines alignment
tolerances. Poor alignment allows vibration, resulting in damage
to the coupling, bearings, rotor, or accessory devices.
8. BELTED APPLICATIONS
It is important that you use the correct sheave size and type. You
must select the proper belts. See the Maximum Shaft Radial
Loading Table on page 14. When you size the sheaves wrong
or tension the belts improperly, premature bearing or shaft failure
may occur. Mount the sheave as close as you can to the motor
housing. If you need help on sheave sizing, call
WHEN REMOVING PULLEYS FROM THE MOTOR SHAFT,
USE A PROPER PULLER. DO NOT PRY PULLEYS OFF BY
LEVERAGE AGAINST THE FRAME. YOU MAY DAMAGE THE
BEARINGS OR THE RETAINER PLATES BY PLACING STRESS
ON THE MOTOR SHAFT RELATIVE TO THE FRAME.
9. OPERATION
After you complete the mounting and alignment steps, you may
make electrical connections. You must follow the connection
diagrams exactly or the motor will not operate.
If turning the wrong way will damage the equipment, verify motor
direction before connecting the load. Monitor motor current during
the first operation of the motor. Compare it to the motor nameplate
value.
Check the motor cooling right after the start-up. Check it at
fifteen-minute intervals until the motor gets to normal temperature
(about four hours at full load).
10. MAINTENANCE
Make the first inspection within a few hours after placing the motor
in service, to catch problems caused by the installation. Check the
motor at least once per month after start-up.
Preventive maintenance means checking the motor often. Make
frequent checks for excess vibration, loose mounting bolts and
belts, odd noises (a steady hum is normal), and high heat output.
