The present magnetic forces are contained in the table in Chapter "Magnetic forces that
occur (Page 30)".
Note
The specified radial forces are the maximum values that occur if the rotor comes into contact
with the stator at one side. For an ideally centric rotor (no eccentricity), the resulting radial
force is zero.
The radial force between a centric rotor and the rotor in contact with the stator can be
linearly converted (calculated air gap, 0.5 mm) depending on the eccentricity.
Depending upon the relative position and the weight of the rotor core, an additional axial
mounting force of about 300 N is required.
