Lifetime of motor bearing
When operating MSM motors within the limits specified for radial
and axial load, the nominal bearing lifetime is L
10h
20,000 ope‐
rating hours.
When exceeding the allowed radial force, the bearing lifetime is reduced to:
L
10h
Bearing service life (according to ISO 281, Version 12/1990)
F
radial
Determined allowed radial force in N (Newton)
F

may never be higher than
the maximum allowed radial force F

3.8 Holding brakes
The following general details are binding for all MSM motors The frame size
depending data of the holding brakes are specified in chapter"Technical data"
●
The values specified in the technical data are typical values excluding
holding torque, trip voltage and rated voltage.
● If the motor was moved, the brake clearance is ±1° or less.
● The power supply of the holding brake is done externally.
● The maximum number of acceleration and braking with the highest al‐
lowed angular acceleration: 10 million
