Maintenance and Troubleshooting
Danger! Danger from electrical voltage!
Before and during assembly, disassembly and repair work, dangerous currents may flow.
Work may only be carried out by a qualified electrician and with the power supply disconnected!
Before carrying out work on the linear motor system, disconnect the power supply and protect it from being
switched back on!
Danger! Danger from strong magnetic fields!
Strong magnetic fields around torque motor systems pose a health risk to persons with implants (e.g. cardiac
pacemakers) that are affected by magnetic fields.
Persons with implants that are affected by magnetic fields should maintain a safe distance of at least
300 mm from torque motor systems.
Danger! Risk of crushing from strong forces of attraction!
Assemble the rotors and stators carefully!
Do not place fingers or objects between the rotors and stators!
The rotor and magnetizable objects may accidentally attract each other and collide!
Two rotors may accidentally attract each other and collide!
The magnetic force of the rotor acting on the object may be as high as several kN, which may cause a
certain part of the body to be clamped.
Do not underestimate the attraction force and operate carefully.
Wear safety gloves when necessary.
At least two people are required to cooperate during operation.
If the assembly steps have not yet reached the installation of the rotor, please place the rotor in a safe and
proper place first.
Never take multiple rotors at once.
Never place two rotors directly together without any protection.
Do not bring any magnetizable materials close to the rotor! If the tool must be magnetized, please hold it
firmly with both hands and slowly approach the rotor!
It is recommended to install the rotor immediately after unpacking!
When installing the stator and rotor, an installation auxiliary device is required to assemble the stator and
rotor individually. Please follow the correct method.
Keep the following tools at hand at any time to release body parts (hands, fingers, feet, etc.) clamped by
magnetic force.
–
Hammer made of non-magnetized solid material (about 3 kg)
Two wedge blocks composed of non-magnetized materials (wedge-shaped sharp angle 10
°
~15
°
, minimum
height 50mm).
Warning! Danger from heavy loads!
Lifting heavy loads may damage your health.
Use a hoist of an appropriate size when positioning heavy loads which are over 20 kg!
Observe applicable occupational health and safety regulations when handling suspended loads!
Motors with stator and rotor fixture can be hung with hanging holes. The strength of the components
should be considered when hanging under any circumstances.
