43 Motors with relubrication system
Depending on the application motors with permanent relubrication or motors with relubrication can be used.
Motors with relubrication system must be maintained and relubricated periodically.
43.1 Relubrication plate and general lubrication instructions
NOTICE:
If the motor is labeled with a lubrication plate, ensure compliance with included data. Otherwise the val-
ues provided in the table apply.
The relubrication plate may include lubrication intervals in accordance with the specific installation direc-
tion, ambient temperature and speed values. A temporary temperature increase may occur for approx. 10
- 20 hours after initial start-up or bearing lubrication.
Bearing lubrication intervals are set primarily with a focus on operational safety. They are therefore gov-
erned by the L1 principle, i.e. these intervals are sufficient for 99% of motors.
43.2 Manual lubrication
43.2.1 Lubricating with running motor
The relubrication should only be carried out with motor running at least n > 300 U/min.
Remove the plug on the grease outlet, where available.
Ensure an unobstructed lubrication channel.
Inject the specified grease amount into the bearing.
Leave tho motor running for 1 - 2 hours to remove excessive grease from the bearing.
Reinsert plug on grease outlet (where applicable).
43.2.2 Lubricating with motor at standstill
Any relubrication should always be carried out with the motor running. Where that is not possible,
lubrication can also be carried out with the motor at standstill.
Inject half the required amount of grease and leave the motor running at full speed for a few minutes
afterwards.
After the motor has come to a complete standstill, inject the remainder of the specified grease into the
bearing.
Reinsert the plug for the grease outlet/outlet valve (where applicable) after 1 - 2 operating hours.
