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 part, the greater the radial force.

Radial force
Note
It is imperative that you observe the radial forces between the stator and rotor as well as the
maximum permissible concentricity error. The maximum permissible concentricity error is
specified in the dimension drawing in the Configuration Manual "SIMOTICS T-1FW6 external
rotor built-in torque motors".
