Maintenance, Dismantling & Assembly
4.1
Maintanence of Linear Motors
The stators and sliders will be shipped with an initial lubrication and are ready for use.
Maintenance of Linear Motors
Maintenance will only be required if the motors run 'dry' or there is a heavy
pollution of the motors.
Under normal industrial conditions (5 days, 8 h / day) a quarterly inspection
is sufficient.
The inspection cycle must be reduced if severe motor loads or deviating
conditions exist. These conditions are for example:
- permanent fouling
- direct sunshine
- low humidity
- outdoor operations
- increased operating temperatures
Inspection of Linear Motors
With inspections of linear motors the following points need to be checked:
- Is the the slider coated in lubricant?
- Is the lubricant not decomposed?
- Is the slider free of scratches or dents and does it move easily
A black 'Zebra'-pattern of lubricant is absolutely normal after short use.
Lubrication of Linear Motors
The lubrication improves the sliding characteristics between the steel surface
of the slider and the polymer bearing of the stator. The lubricant prevents
corrosion on the slider surface. Only the specified lubricant may be used.
Before lubrication the slider and stator should be clean, as far as possible.
Do not use harsh brushes, sandpaper, or similar things for cleaning.
Cleaning solutions with solvent additives should not be used neither.
To lubricate, dismantle die slider and carefully pull it out of the stator. Use
small amounts of methylated spirit or alcohol and a soft tissue to gently clean
the stator and slider. Coat the slider with a thin coat of fresh lubricant and
gently put it back into the stator. Make sure to install the slider in the correct
direction. If the slider cannot be dismantled, then cleaning and lubrication is
to be done on the extruding ends of the slider.
