6. Maintenance
The motor does not need any maintenance. Opening or disassembling of
the motor would cause a forfeit of warranty claims! It could be also very
dangerous, due to very strong magnets on rotor!
Though, it has to be considered that no foreign objects at all can enter the interior of
the drive.
Further, it is necessary to protect the motor from humidity, dirt, paint, glues etc. If
this is ignored, a proper functionality of the motor cannot be guaranteed, and irreparable
damages are possible. In case of damage, ship the drive back to the manufacturer for
repairs. Unintended handling leads to secondary damages.
Keep magnetic memory cards or electronic devices out of the rotor’s close
-up range,
because the alternating magnetic field can cause a delete of data. Be also careful with
medical devices (e.g. pacemakers) which are sensitive to alternating magnetic fields.
The small gap between the stator and the magnets of the rotor function-bound has a
thickness of only a few tenth of millimeter. Here, the danger of foreign objects
accumulating in this gap exists but can be heard by scratching-sounds. In this case
spinner should be removed and the motor should be blown-out with compressed air. Do
not at all simply keep on using the drive. Be especially aware of cuttings which can almost
irremovably stick to the magnets. In this case, the only thing that helps is a disassembly
of the drive by the manufacturer.
