Spare Parts; Environmental Requirements - ABB MT Série Manuel D'installation, D'exploitation Et De Maintenance

Grease with the correct properties is available from all
major lubricant manufacturers.
Admixtures are recommended, but a written guarantee
must be obtained from the lubricant manufacturer
especially concerning EP admixtures, that admixtures
do not damage bearings or the properties of lubricants at
the operating temperature range.
WARNING
Lubricants containing EP admixtures are not
recommended in high bearing temperatures in
frame sizes 280 to 400.
If the ambient temperature is below -25°C or above
+55°C, or bearing temperature is above 110°C, consult
ABB Sales Office regarding suitable grease.
The following high performance grease can be used
•
Esso Unirex N2, N3 or S2 (lithium complex base)
•
Mobil Mobilith SHC 100 (lithium complex base)
•
Shell Albida EMS 2 (lithium complex base)
•
SKF LGHQ 3 (lithium complex base)
•
Klüber Klüberplex BEM 41-132 (special lithium
base)
•
FAG Arcanol TEMP90 (calsium polyurea base)
•
FAG Arcanol TEMP110 (lithium complex base)
Lubrication intervals for other grease fullfilling the
required properties, contact your local ABB Sales
Office.

NOTE!
Always use high speed grease for high speed machines
and some other models, e.g. M2BA 355 and 400 2-pole
machines, where the speed factor is higher than 400 000
(calculated as Dm x n where Dm = average bearing
diameter, mm; n = rotational speed, r/min).

The following grease can be used:
•
FAG L69 (polyurea base)
•
Klüber Klüber quiet BH 72-102 (polyurea base)
•
SKF LGHP2 (polyurea base)
If other lubricants are used, check with the manufacturer
that the qualities correspond to those of the above
mentioned lubricants, or if the compatibility of the
lubricant is uncertain, contact your local ABB Sales
Office.
Frequency converter drives
Higher speed operation, e.g. in frequency converter
applications, or lower speed with heavy load will require
shorter lubrication intervals. Consult your local ABB
Sales Office in such cases.
Typically a doubling of speed will require a reduction of
lubrication intervals to approx. 40 % of values tabulated
above.
WARNING
The constructional maximum speed of the motor
must not be exceeded.
Suitability of bearings for high speed operation must be
checked.

Spare parts

When ordering spare parts, the full type designation and
product code, as stated on the rating plate, must be
specified.
If the machine is stamped with a serial manufacturing
number, this should also be given.
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.

5. Environmental requirements

Noise levels
Most of our motors have a sound pressure level not
exceeding 82 dB(A) refer to 50 Hz sinusoidal supply
conditions, tolerance ± 3 dB(A).
Values for specific machines can be found in the
relevant product catalogues.
For sound pressure levels for 60 Hz sinusoidal supply
and with non-sinusoidal supplies, contact ABB Sales
Office.
Sound pressure levels for all machines having separate
cooling systems and for series M2F*/M3F*, M2L*/M3L*,
M2R*/M3R*, and M2BJ/M2LJ are indicated in separate
Manuals.
