11.6 Disposing of permanent magnets
If the entire motor is melted down, no special action is required for the permanent magnets.
Remove all cables before the melting process.
Demagnetizing the motor
If the motor is disassembled and dismantled, the permanent magnets must be demagnetized.
To do this, the motor is heated up to 350 °C so that during and after disposal, the rotors do
not represent any danger. The disposal must be carried out by an authorized waste disposal
company.
Note
Removing the permanent magnet rotor
Injury and material damage can occur if the permanent magnet rotor is incorrectly removed.
Only authorized workshops and waste disposal companies are permitted to remove the rotor.
