4.1 Maintenance of main FES components
4.1.1 Motor maintenance
We designed the FES motor such that it does not require any special maintenance.
Warning:
Opening or disassembling the motor can void the warranty! It is
very dangerous due to powerful magnets installed on the rotor!
To ensure proper operation of the motor, please consider the following:
−
Make sure the
motor compartment is clean and completely free of all
foreign objects
that could enter the interior of the drive.
−
It is necessary to
protect the motor from humidity, dirt, paint, glue,
etc.
Proper functioning of the motor cannot be guaranteed, and irreparable damage is
possible if you ignore this.
−
In
case of damage
, ship the motor back to the manufacturer for repair.
Unintended handling leads to secondary damage.
Note:
Strong magnetic field of the magnets in the rotor can erase the data on
magnetic memory cards or electronic devices and interfere with sensitive
medical devices (e.g., pacemakers).
Keep them away from
the rotor’s close
-up
range!
The gap between the stator and the rotor magnet's function-boundary is only a few
tenths of a millimeter thick. The danger of foreign objects accumulating in this gap exists
and makes itself noticeable by scratching-sounds. In this case, remove the spinner, and
blow out the motor with compressed air. Stop using the system and prevent the motor
from running until you have cleaned it. Be especially aware of metal shavings, which can
firmly stick to the magnets. If this is the case, the drive needs to be disassembled by the
manufacturer.
