5. If the stress of the rotor core is not relieved after mounting, rub dismantling oil in the
joined surfaces
③
e.g. SKF LHMF 300.
6. The rotor core and spindle shaft are mounted using thermal joining.
NOTICE
Damage to the permanent magnets of the rotor
If the rotor temperature exceeds 150° C (140° C for APM rotors), the permanent
magnets in the rotor will be demagnetized irreversibly.
•
Ensure the rotor is not heated above 150° C (140° C for APM rotors) by checking the
rotor temperature with a temperature-reactive dye or a temperature measuring
device.
• Inductive heating of the rotor is not permissible.
NOTICE
Danger of damage to the rotor banding caused by impermissible temperatures
APM rotors have a banding (composite fiber) around the external diameter of the rotor
that can be damaged by impermissible temperatures during mounting.
• Comply with the permissible temperatures during mounting.
NOTICE
Danger of bearing damage on the spindle shaft
Low temperatures can damage the bearing of the spindle shaft.
• Use the cold process only when the bearing lubricant is certified for low
temperatures.
Note
A hot box or Dewar vessel must be kept in the immediate vicinity of the mounting
location.
Three processes are deployed.
Hot process (shrinkage) Cold process (stretching) Combined cold-hot process
The tempered spindle shaft is
inserted into the rotor core
that has been heated up.
The rotor core is inserted over
the spindle shaft that has been
cooled down.
