Danger when openly storing rotors
Danger when openly storing rotors
The rotors of the synchronous machines contain permanent magnets with high magnetic flux
densities and strong attraction forces to ferromagnetic bodies.
You must observe the following safety instructions to prevent death, injury or material damage:
• It is not permissible that persons with heart pacemakers come close to openly stored rotors.
• Secure openly stored motors so that they cannot come into contact with one another.
• Avoid that openly stored rotors knock against metal objects which could potentially damage
• Data stored on electronic data carriers can be destroyed.
The synchronous machines have the same operational reliability and require less
maintenance than standard three-phase induction motors. When installed, the permanent
magnets are insensitive to shock, knocks and aging.
The rotors of synchronous machines can be removed and openly stored without the
magnetic circuit having to be closed. When installing and removing, the rotor attaches itself
to the stator as a result of the integrated permanent magnets. When removed, protect the
rotor against pollution by magnetic waste, for example with a plastic bag.
If the paint is damaged, it must be repaired in order to protect the unit against corrosion.
Note
Paint system
Contact the Service Center before you repair any damage to paint. They will provide you with
more information about the correct paint system and methods of repairing paint damage.
