Rotor sleeves
Note
Built-in motors without rotor sleeve:
The force is transmitted without any play through a friction-locked connection. Larger shaft
diameter diameters are achieved due to the fact that there is no rotor sleeve. Generally, it is
not possible to release the group (rotor and stator) using the version without sleeve.
Built-in motors with rotor sleeve:
The rotor is located on an inner sleeve with a step interference fit. The press fit can be
released using pressurized oil without this influencing the joint surfaces.
The spindle manufacturer mounts the rotor on the spindle using a thermal shrinking
procedure.
NOTICE
Damage to the rotor permanent magnets due to excessively high temperatures
If the temperature exceeds 140 °C on APM motors, the permanent magnets in the rotor will
be irreversibly demagnetized.
•
Prevent this temperature from being exceeded on APM rotors by checking the rotor
temperature using a temperature-reactive dye or a temperature measuring device.
• Inductive heating of the rotor is not permissible.
To ensure torque transmission without any play, in the area of the interference fit, the
spindle must be machined with the specified dimensions and tolerances. Additional
information is provided in the dimension drawing in Chapter "Dimension drawings
(Page 147)".
