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.

Bearing tube
Wiper
Check + Possibly replacing the tube and the wipers in case
of visible wear. (See section 6.2)
Slider
Check whether the slider surface is clean and not scratched.
Scratched sliders must be replaced, otherwise clean the
slider. (See instruction, section 3.2)
Electrical connection
Tighten the electrical connection between cable and stator.
Tightening torque: 0.6 Nm (Q-, J-connector) according to
section 5.3 "Connector".
Fluid cooling (if available)
Check whether the cooling circuit is permanently connected.
Tightness
•
Check whether the mounting flanges are firmly bolted to
the stator without gap.
•
Tightening torque:
Cylinder screw M6 (6 Nm)
Ease of movement
If friction is felt during movement, the motor must be stopped
immediately.
Check the alignment of the load bearing and slider.
7.3.2 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 slider and stator with a soft disposable paper, ideally with the help of LU06 cleaning spray (or
acetone or benzene). Available cleaners in the food industry may also be used. However, these should
not leave any residues.
•
Finally, slider should be inserted according to the chapter 3.2
“Instructions for installing the linear motor”.
7.3.3 Cleaning agent
All LinMot stainless steel motors have a protection class of IP69K. 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 (Polyamide) and the wiper material (H-ECOPUR) must be checked.
