Installation Guide Linear Rotary Motors
8 Maintenance and Test Instructions
8.1 Maintenance
The linear rotary motors are provided with initial lubrication at the factory. Maintenance / cleaning is only
necessary if the motors are heavily soiled.
Under normal industrial, Central European conditions (5-day week with 8 hours of operation per day), one
inspection at the recommended interval is sufficient.
The inspection cycle must be shortened if there are heavy motor loads or deviating conditions. These
conditions are e.g.:
•
Permanent fouling
•
Direct sunshine
•
Low Humidity
•
Outdoor operation
•
Increased operating temperature
•
Other special environmental conditions
Maintenance or disassembly of the linear rotary motors may only be carried out by trained companies:
•
LinMot
•
Companies qualified by LinMot
If the linear rotary motor is not opened by one of the above-mentioned companies, the
warranty claim will be invalidated.

8.1.1 Preventive Inspection every 6'000h
To ensure the smoothest possible operation, a preventive inspection is recommended every 6,000 hours of
operation or after one year under normal industrial, central european conditions.
When inspecting the motors, the following points must be checked:
c) Visual inspection of all wearing parts such as seals and wipers
d) Does the motor operating temperature or the motor current consumption correspond to the expected
empirical values?
e) Are any suspicious or unknown noises or vibrations recognisable during operation?
f)
Is smooth rotary and linear movement (attention with MagSpring) possible when de-energised?
g) Is there a light film of grease on the extended linear rotary shaft?
If one of the above points no longer applies, maintenance by LinMot or by a company qualified by LinMot is
recommended (see chapter 8.1.2).
8.1.2 Needs-based maintenance
During needs-based maintenance, the linear rotary motor is completely disassembled, cleaned and
relubricated. Among other things, the steps listed below are carried out:
•
Replacement of seals and wipers
•
Cleaning / lubrication of mechanically moving parts
•
Replacement of the linear rotary shaft
•
Replacement of all ball bushings / plain bearings / couplings / carriers
•
Replacement of all air connections and seals
•
Revision of the linear motor slider
•
Final test & functional test of linear rotary motor
•
Leak test for vacuum & compressed air with existing "air feed-through" option
•
Replacement of the pneumatic cylinder if the "pneumatic pusher" option is available
