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
-
Check the condition of the manifold runner. An uneven or faulty runner wears down the brushes more quickly and
indicates that the working conditions (e.g. load) or environmental conditions (e.g. chemical agents) require changes
to the quality or number of brushes.
-
Check that the eccentricity of the manifold does not exceed 0.03 mm and that it has no protruding segments or
holes.
-
Check the wear and tear of the brushes and their condition.
-
Check that the brushes slide across the manifold evenly.
-
Check that the insulation is greater than 60MOhm in the excitation and 10MOhm in the armature, especially in
environments with high humidity levels.
-
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
Cleaning of the fan and air filter
It is important to keep the fan wheel as clean as possible. To do so, apply compressed air to its surface on a regular basis to
ensure that there are no unwanted particles deposited on it.
The frequency of the cleaning process will depend on the local and environmental conditions that affect the motor, as well as the
frequency with which the motor is used.
MOVING ROTATING PARTS
During the motor fan wheel cleaning operation, the customer is responsible for taking the necessary precautions to avoid
accidental contact with the rotating parts.
