Maintenance of linear motors
The person responsible for the operation of the motors must ensure that the specified maintenance work is
carried out. The following maintenance schedule is designed for the operating conditions in the food industry
with contact of liquid media. The inspection cycle is 2.5 million movement cycles or 1500 friction-kilometer.

Slider bearing
Wiper
Check and, if necessary, replace the bearing sleeves and
wiper rings (see section 5.2 «Bearing kit»).
Slider
Check that the slider surface is clean and not scratched.
Scratched sliders must be replaced, otherwise
Clean the slider. See the following section.
Electrical connection
Tighten the electrical connection between cable and stator.
Tightening torque: 0.6 Nm (R-Connector)
Ease of movement
If friction is felt during movement, the motor must be stopped
immediately.
Check the alignment of the load bearing and slider.
6.2.2 Cleaning
•
Pull the sliders carefully out of the stator.
Attention!:
Strong magnetic attraction forces (note safety instruction “contusions”
on page 5.)! Use non-magnetic material (e.g. wood) to cover close-by iron constructions.
•
Clean the slider and bearings with a soft disposable paper, using for example acetone or benzene
cleaner. Common cleaning agents used in the food industry may also be used. However, these should
not leave any residues.
•
Then, if the application allows, the slider and the bearings should be lubricated.
The bearings are each greased with 1 g grease LU07. There should only be a light layer of grease on
the inside.
Note!:
Avoid overlubrication!
Finally, grease the slider according to paragraph 3.2 "Assembly of the linear motor".
6.2.3 Cleaning agents / Lubricants
All LinMot stainless steel motors have a protection class of IP69. Standard cleaning agents in food and
pharmaceutical industries with usual concentration and amount, can be used for the cleaning. If necessary,
compatibility with the bearing material (PEEK / PPS) and the wiper material (H-ECOPUR) must be checked.

7 Storage, transport, installation altitude
•
Sliders are to be stored and transported only in the plastic containers (with cardboard inlay) provided for
this purpose, or already installed and secured in LinMot P stators.
•
Remove the slider from this plastic containers only for assembling.
•
The storage area must be dry, dust-free, frost-free and vibration-free.
•
Prescribed storage temperature: -
15 °C…70 °C
•
The motor must be protected against extreme weather conditions.
•
The air in the storage area must not contain any harmful gases.
•
The max. installation altitude is 4'000 m above sea level.
•
From 1'000 m, derating of 1 °C per 100 m is to be considered for air cooling.
