Three-phase synchronous motor, water-cooled
English
If equipped with the optional shaft sealing ring, this must be checked regularly to ensure that it is
functioning correctly (leaks).
Note on thrust-bearing motors:
An inspection hole for leak oil from the thrust-bearing housing is
located on the bottom of the A-side bearing end plate near the feet (see
Appendix 3
–
Fig. 1
). If
oil exits here, the shaft sealing rings of both sealing points must be replaced.

Maintenance
Depending on the operating conditions, (e. g. mode, temperature, speed and load), the service life
of the bearings and sealing elements can differ greatly.
Maintenance work (except for oil changes) must be carried out by Baumüller or a specialist
company commissioned by Baumüller.
In the case of troublefree operation, we generally recommend the following maintenance
procedures:
• replacement of the
bearings
after 20000 running hours (The bearings are designed for a
calculated service life of 20000 running hours)
• In case of hollow-shaft motors: replacement of the
encoder
,
encoder-bearing
and
toothed
belt
after 20000 running hours.
In the case of
thrust-bearing motors
, we generally recommend the following maintenance
guidelines:
• First
oil change
after about 5000 operating hours. All subsequent oil change after 10000
operating hours. Oil lubrication (sump) with
high-performance synthetic gear oil
–
"Klübersynth GH6-
320” (Klüber Lubrication) or "Omala S4 WE 320"(Shell) or „Degol GS 320“
(ARAL).
• A change of shaft sealing, in case of presence, must be implemented when leakage occurs.
Note on oil changes:
Do not begin draining the oil until the motor is secured and the housing parts have cooled down to
room temperature!
For quicker emptying, unscrew the filler and drain plugs.
(
compare to
Appendix 3
– Fig. 8
).
Fill the thrust-bearing housing with the appropriate oil; the motor should be horizontal when doing
so. The required oil level is reached when the oil drips out of the opened oil level screw (overflow
principle).
For the approximate oil quantity, please refer to
Appendix 3
.
If an optional
brake
is fitted, it is essential that it is replaced when its wear limits are reached.
Caution!
The specifications of the technical instructions TAM 00697 must be followed during
maintenance and servicing on motors which are used for safety-oriented applications.
