Radial forces between the stator and rotor
The following table shows the active radial forces (in N per 0.1 mm centering error) between
the stator and rotor. The longer the active component, the greater the radial force.
Table 4- 1 Radial forces in N/0.1 mm with radial centering errors during installation
Active length in mm
30 50 70 100 150
1FW605 80 140 190 270 400
1FW606 110 180 250 350 520
Note
It is imperative that you observe the radial forces between the stator and rotor as well as the
maximum permissible concentricity error. This is specified in the dimension drawings in the
Configuration Manual "Naturally cooled built-in torque motors 1FW6".
Example
For a torque motor 1FW6053-0LB10-xxxx (active part length 100 mm) the eccentricity is
0.2 mm for example.
The active radial force as a result of this centering error is, therefore:
Axial forces between the stator and rotor

Note
At the beginning and at the end of the insertion process, the axial forces of attraction
between the stator and rotor are 4x to 5x higher.
