equipment and these aspects must be taken care of by the customer.
10.5.3 Permanent magnets
If the permanent magnet synchronous machine is melted down as a whole, nothing needs to be
done to the permanent magnets.
If the machine is dismantled for more thorough recycling and if the rotor must be transported
after it, it is recommended that the permanent magnets are demagnetized. The demagnetization
is done by heating the rotor in the oven until the permanent magnets reach a temperature of
+300 °C (572°F).
WARNING: Magnetic stray fields, caused by an open or disassembled permanent magnet
synchronous machine or by a separate rotor of such a machine, may disturb or
damage other electrical or electromagnetic equipment and components, such as
cardiac pacemakers, credit cards and equivalent.
