Motors are balanced according to ISO1940:1998
standard, balancing grade G2.5.
M3BM motor catalogue ratings can be re-stamped
as follows. Motor construction will not be changed
but a new rating plate and data sheet can be created
with variant code 002. In all the below cases or their
combinations, please contact ABB for correct motor
size and motor data. Bearing re-lubrication intervals as
shown in this catalogue are valid also for re-stamped
motors.
Output
Output can be re-stamped downwards from the
catalogue data.
Voltage
Voltage can be re-stamped downwards up to 10%
from the motor nominal voltage in the catalogue. Motor
output has to be de-rated so that the motor absolute
temperatures will not be higher compared to catalogue
data.
Ambient temperature
Motor can be de-rated to higher ambient temperature.
Maximum ambient temperature is 55 °C. The
output has to be de-rated so that motor's absolute
temperatures will not be higher than the catalogue
data.
Altitude
Motor can be de-rated to higher altitudes than
standard 1000 meters above sea level. There are
different maximum altitude limits for different motors
depending on voltage level. The motor output has to
be de-rated so that the absolute temperatures of the
motor will not be higher than the catalogue data.
Note: M3GM (Ex) motors for higher than 1000 meters
above sea level altitude can be offered only case by
case from the manufacturing unit.
