Three-phase synchronous motor English
6.1 Inspection
Depending on the severity of soiling on site, cleaning will have to be carried out regularly to guarantee
the continuous adequate dissipation of heat. The flow rate and the pressure ratio of the cooling system
must be checked.
If an optional brake is fitted, wear limits are specified (e. g., maximum permissible operating air gap,
maximum number of emergency braking operations). The actual degree of wear on the brake must be
checked at regular intervals. When the permissible wear limits have been reached, the brake must be
replaced (see Section 6.2).
If an optional shaft sealing ring is used, it must be checked at regular intervals to ensure it is functioning
correctly (leakage).
6.2 Maintenance
The service life of the bearings and sealing elements can differ greatly depending on the operating
conditions, (e. g. operating mode, temperature, speed and load).
In the case of trouble-free operation, we generally recommend the following maintenance procedures:
• Replacement of the bearings after 20.000 running hours (the bearings are designed for a calculated
service life of 20.000 running hours)
• Replacement of the shaft-sealing ring, if applicable, if a leakage occurs.
If an optional brake is fitted, it is essential that it is replaced when its wear limits are reached.
The maintenance work is to be undertaken by Baumüller or a specialist organization authorized by
Baumüller.
The independent maintenance works of an operator are the following:
The cleaning of the motor surfaces and of the air channels.
The replacement or cleaning of the filter mats when using dust filters (as at motor size 132):
Dust filters should generally be cleaned or replaced after 100 operating hours. If there is high
pollution the service intervals are to be reduced.
Filters polluted by dry dirt can be cleaned by vacuuming, blowing them out or beating them.
Filters polluted by wet dirt can be rinsed out in lukewarm water while adding a commercially
available washing agent and then drying them.
Note: If the filter mats must be replaced then use original replacement filters of the motor
manufacturer, only. These can be requested from Baumüller under specification of the motor
number as well as of the order number (see type plate).
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.
7 Disposal
The motor must be disposed of in accordance with the relevant national and local regulations within the
framework of the normal recycling process.
Note: The motor rotors include rare earth magnets with a high magnetic energies. Refer to the note
in Chapter 1.2
The encoder electronics (if an absolute value encoder was integrated optionally) must be disposed of in
the proper manner as electronic scrap.
