NOTE!
Always use high speed grease for high speed
machines and some other models, e.g. M2 BA 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)
– Lubcon Turmogrease PU703 (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
Offi ce.
WARNING
Especially in high rotational speed (the speed
factor > 400000) over greasing may cause
damage.

4.1.7 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 Offi ce 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 (see table 2).
Suitability of bearings for high speed operation must be
checked.

4.1.8 Spare parts

When ordering spare parts, the full type designation
and product code, as stated on the rating plate, must be
specifi ed.
If the machine is stamped with a serial manufacturing
number, this should also be given.
For more information, please visit our web site
www.abb.com/partsonline.

4.1.9 Rewinding

Rewinding should always be carried out by qualifi ed
repair shops.
Smoke venting and other special motors should not be
rewound without fi rst contacting ABB.

requirements

5.1 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 specifi c 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
Offi ce.
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 Manuals.
