Inspection and maintenance
Working on the electric motor:
Carry out all work on the electric motor only when the motor is stationary, de-energized
and cooled down. After inspection or maintenance, retighten all connections loosened
during work on the motor, such as screws, etc.
It is imperative that you observe the technical instructions in the respective chapters of
these commissioning and maintenance instructions when carrying out the work.
During maintenance work, it is essential to observe the safety instructions as they also
apply to the commissioning of the motor (see
chapter 5.1
)
Attention!
If the optional holding brake is installed, it may not perform any safety function during
work on the motor (such as holding loads)
6.1 Inspection
Depending on the local degree of soiling, regular cleaning must be carried out in order to ensure
sufficient dissipation of the heat loss in the long term.
If a brake is optionally installed, wear limits are specified. (Such as maximum permissible operating
air gap, limited number of emergency braking operations) The current wear degree of the brake is
to be checked regularly. When permissible wear limits have been reached, the brake must be re-
placed (see
chapter 6.2
).
If a shaft sealing ring is optionally used, this must be checked regularly for proper functioning (leak-
age).
6.2 Maintenance
Depending on the operating conditions (such as operating mode, temperature, speed and load), the
service life of the bearings and sealing elements can vary considerably.
For a failure-free operation, we recommend general maintenance guidelines:
- The bearing must be changed after approx. 20,000 operating hours. (The bearing arrangement is
designed for a calculated bearing service life of 20,000 operating hours).
- Replacement of the shaft sealing ring, if present and if no leakage could be detected during previ-
ous inspections, after approx. 5,000 operating hours.
If a brake is installed as an option, it must be replaced when its wear limit is reached.
The maintenance work is to be carried out by Baumüller itself or by one of the assigned companies
Attention!
For motors which are used in safety-related applications, it is imperative that the specifica-
tions of the technical instruction TAM 00697 are observed during maintenance and service.

Disposal
The motor is to be disposed of in the normal recycling process in accordance with national and local
regulations.
