= 20.000 h, in case of utilization after S1-100K and max. load factor 90%
during the runtime.
When exceeding or not complying with these conditions, a reduced
service life is to be expected.
Explanation of radial and axial force
During operation, both radial and axial forces act upon the motor shaft and the
motor bearing. The permissible radial force F
R
in distance x from the shaft shoul-
der and the mean speed is specified in the radial force diagrams.
Fig. 4-11: Point of action of radial force F
R
and axial force F
A
The axial force values are the minimum permissible axial forces F
A
without limi-
tations. A detailed dimensioning is only possible if more boundary conditions
are known:
● Axial and radial force with force application point
● Installation position (horizontal, vertical with the shaft end pointing to the
top or bottom)
● Mean speed
Radial force diagrams are specified in the project planning manual "DOK-MO-
TOR*-MS2N*******-PRxx-xx-P"
4.2.12 Frame size, installation type
The motors can be installed horizontally and vertically with the shaft end point-
ing to the top or bottom. The installation variants correspond to IM-code accord-
ing to EN 60034-7 for frame size and installation type.
