Fläkt Woods three phase asyncronous motor
Manufacturer: ABB
Lubrication intervals for vertical machines are half of the
above values.
The amount of grease stated in the table should be doub-
led if an automatic regreasing system is used.
The table values are based on the motor running at rated
output in an ambient temperature of about + 25 °C (approx.
80 °C bearing temperature). The values should be halved
for 15 °C increase in bearing temperature and may be
doubled for 15 °C decrease in ambient temperature.
Higher speed operation, eg in frequency converter applica-
tions, or lower speed with heavy load will require shorter
lubrication intervals. Consult 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.
Suitability of bearings for high speed operation must also be
checked.
WARNING!
The maximum operating temperature
of the grease and bearings must not be
exceeded.
Lubricants
When regreasing, use only special ball bearing grease
with the following properties:
- good quality grease with lithium complex soap and
with mineral- or PAO-oil
- base oil viscosity 100-150 cST at 40°C
- consistency NLGI grade 2 or 3
- temperature range -30°C - +120°C, continuously.
Grease with the correct properties is available from all
the major lubricant manufacturers.
The following (or similar) high performance grease can
be used
• EssoUnirex N2 or N3
• Shell Albida EMS 2
• SKF LGHQ 3
• Mobil Mobilith SHC 100
• Klüber Kluberplex BEM 41-132
• BP Energrease LC2
NOTE!
Always use high speed grease for high speed
machinens and some other models, e.g. M2_ 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, rpm). The following,or similar, types of
grease can be used:
• Kluber Asonic GHY 72
• Kluber Asonic HQ 72-102
• Shell Albida EMS 2
• Esso LT2
• Mobil Mobilith SHC 100
The following normal type of grease can be used if the
regreasing interval is halved (these types of grease should
not be used when bearing temperature is above 100 °C).
• Esso
Beacon 2 or 3
• Shell Alvania RL2 or RL3
• SKF LGMT 2 or 3
• Mobil Mobilux 2
• Kluber Centoplex 2
• BP Energrease LS2
If the make of grease is changed and compatibility is
uncertain, consult ABB Sales Office.
Highly loaded and/or slowly rotating bearings require
EPgrease.
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.
