6.2.1
Basic inspection
After assembling the motor or after repairing a breakdown, the motor must be inspected approximately every 500
operating hours or at least every six months.
This inspection must consist of basically the following:
With the machine on:
-
Check that the motor works according to its rated mechanical and electrical values and that there
are no strange noises, vibrations or irregular rotation.
With the machine off:
-
Check that no cracks appear in the motor fastening elements.
-
Check that the connection terminals in the terminal box maintain an adequate fastening torque as
specified in the Table 20.
-
If faults are found during the inspection, they must be corrected immediately.
Besides this basic inspection, a number of maintenance tasks must be carried out to ensure that the motor has a
long service life. The maintenance operations recommended by VASCAT are as follows:
6.2.2
Replacement of bearings
Both the bearings that have been greased for all their service life and the hermetic parts that are subjected to
wear and tear (seals and joints, etc.), where applicable, must be replaced after 20,000 operating hours.
Bearings of the same type as the originals must be installed. Standard bearings for each motor type may be
consulted at Table 17.
The procedure for replacing bearings must be carried out as follows:
1.
Disassemble the motor from its location and place it in a safe and clean place.
2.
Remove the accessories (brake and/or encoder, where applicable) from the motor very carefully so as
not to damage them and then remove the fan. See following sections for more details.
3.
Unscrew the motor seals and covers and remove them.
