7. After Sales Support

7.1 Spare parts

When ordering spare parts, the motor serial number, full
type designation and product code, as stated on the rating
plate, must be specified.

For more information, please visit our web site

www.abb.com/partsonline.

7.2 Rewinding
Rewinding should always be carried out by qualified repair
shops.

Smoke venting and other special motors should not be

rewound without first contacting ABB.

7.3 Bearings
Special care should be taken with the bearings. These
must be removed using pullers and fitted by heating or
using special tools for the purpose.

Bearing replacement is described in detail in a separate

instruction leaflet available from the ABB Sales Office.

8. Environmental requirements

8.1 Noise levels

Most of ABBs motors have a sound pressure level not
exceeding 82 dB(A) at 50 Hz .

Values for specific machines can be found in the relevant

product catalogues. At 60 Hz sinusoidal supply the values
are approximately 4 dB(A) higher compared to 50 Hz
values in product catalogues.

For sound pressure levels at frequency converter supply,

please contact ABB.

Sound pressure levels for all machines having separate

cooling systems and for series M2F*/M3F*, M2L*/M3L*,
M2R*/M3R*, M2BJ/M3BJ and M2LJ/M3LJ are indicated in
separate additional manuals.
