4.1 Maintenance of main FES components
4.1.1 Motor maintenance
FES motor is designed so that practically does not need any special maintenance.
Warning:
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 can not be guaranteed and
irreparable damages are possible. In case of damage, ship the motor back to the
manufacturer for repairs. Unintended handling leads to secondary damages.
Note:
Keep magnetic memory cards or electronic devices out of the rotor’s
close-up range, because the strong magnetic field can cause a delete of data.
Be also careful with medical devices (e.g. pacemakers) which might be
sensitive to strong magnetic fields.
The small gap between the stator and the magnets of the rotor function-bound has
a thickness of only a few tenth millimeters. 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.
