5.15 MOTOR LUBRICATION

The induction-type squirrel cage motors have antifriction
ball or roller bearings front and rear. At periodic intervals
they require relubrication.

1000 hours ......................................all TEFC drive motors
2000 hours .........all ODP drive motors and all fan motors
Relubrication amount
Motor Frame Size

Improper lubrication can be a cause of motor bearing
failure. The quantity of grease added should be carefully
controlled. The smaller motors must be greased with a
lesser amount of grease than larger motors.
!
CAUTION
Overgreasing can be a cause of bearing and
motor failure. Make sure dirt and contaminants
are not introduced when adding grease.
Procedure for relubrication
!
CAUTION
Grease should be added when the motor
is stopped and power disconnected.
When regreasing, stop motor. Disconnect power; lock out
and tag. Remove outlet plugs (or spring-loaded grease
relief plugs if present). The outlet plug may not be
accessible on the fan end of some TEFC motors.
