Demagnetizing the rotors
Waste disposal companies that are authorized to demagnetize rotors use a specially designed
disposal furnace. The insides of the disposal furnace consist of non-magnetic material. The
rotors are put in the furnace in a solid, heat-resistant container made of non-magnetic material
and left in the furnace during the entire demagnetization procedure. Demagnetization is
achieved by heating the rotor in the furnace until the permanent magnets have reached a
temperature of 350 °C.
NOTICE
Emissions
Exhaust gas that is released must be collected and rendered harmless without damaging the
environment.
Note
Authorized waste disposal companies
Information regarding authorized waste disposal companies and workshops can be obtained
from the Siemens Service Center (Page 117).
