6.2 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.
6.2.1 Maintenance Schedule
When
What
Task
Every 2.5 million
movement cycles
or
1500 friction-
kilometer
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.
•
Afterwards, lubricate the bore of the stators with about 2-3 g (0.1 oz) grease LU02. There should only be
a slight film of lubricant.
Note:
Do not over lubricate!
•
Finally, grease the slider according to paragraph 3.2 "Assembly of the linear motor".
6.2.3 Cleaning Agent
/ Lubricant
All stainless steel motors from LinMot have an IP69 protection class. They can be cleaned with the usual
cleaning agents, in the usual concentration and quantity as used in the food and pharmaceutical industry. If
necessary, compatibility with the bearing material (PEEK / PPS) must be checked.

7 «Wash-Down» Advice
•
Cleaning should only be carried out by qualified personnel.
•
Cleaning should only be carried out when the machine is not in motion.
•
Observe the limits of the IP69K standard for pressure, temperature, angle and distance of the cleaning
agent jet.
•
Observe the specifications for chemical compatibility for the materials used in the motor. See chapter
3.7.
•
If the plug connection is also in the cleaning area, please refer to the details in the chapters "Motor
Cable" and "Connectors".
•
Do not use wire brushes or scrapers to clean the motor surface and cables. Remove dirt only by hosing
down (comply with IP69K limits!) or wiping off.
