AC Induction Motors
Maintenance
Amount of grease to be added to motors is shown in
. See
for relubrication interval. Use Chevron SRI-2 or equivalent
grease unless motor nameplate specifies special grease.
Table F
Coupled/Belted or Tandem Duty Grease Amounts
Using the table below, determine service condition on the basis of the
most severe operating parameter (i.e. temperature, bearing load,
atmosphere, or operating hours per day).
Table G
Service Condition
1
Motors must be specially designed for operation in ambient outside the range of –25 to 40 degrees C
(–13 to 104 degrees F). Special grease is required.
2
"EXTREME" service conditions are rare in actual practice. Corresponding lubrication cycles should
therefore be applied with caution. In addition, it is advisable to check with Allen-Bradley for related special
instructions.
!
ATTENTION: Internal parts of this motor may be at line
potential even when it is not rotating. Before performing
any maintenance which could result in contacting any
internal part, be sure to disconnect all power from the motor.
Failure to observe this precaution could result in severe
personal injury or death.
