Magnetic forces that occur in stators with permanent magnets (synchronous version)
The magnitude of the present magnetic forces is motor-specific.

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 upon the relative position and the weight of the rotor core, an additional axial
mounting force of about 300 N is required.
6.5.3 Mounting the motor spindle
The following chapter describes the mounting of the spindle housing with spindle shaft onto
the motor spindle.
Danger of damage to the banding of APM rotors (synchronous version).
The banding (composite fibers) must not be damaged and must not come into contact with
the stator bore.
• Remove the protective film only immediately before mounting.
• Use an assembly film.
• Always use a centering assembly fixture for mounting.
Precondition
● All personal protection equipment is available and must be worn.
● All installation equipment and resources are available.
