Disposal

11.3 Dismantling the machine

11.3 Dismantling the machine
Dismantle the machine using the general procedures commonly used in mechanical
engineering.
Machine parts can fall
The machine is made up of heavy parts. These parts are liable to fall during dismantling.
This can result in death, serious injury or material damage.
Before you release any machine parts, secure them so that they cannot fall.
Dangerous voltage when the rotor rotates
There are dangerous voltages at the terminals while the machine rotor rotates and
immediately afterwards.
You must observe the following safety instructions to prevent death, injury or material
damage:
• Do not touch the terminals while the rotor is rotating and immediately afterwards.
• To discharge the winding, after the rotor comes to a standstill, connect the winding to
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
• 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
• 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.
