● The mounted rotary axis must always be able to move without hindrance.
Examples of axes that cannot necessarily be checked by hand:
–
Large axes with a high friction torque
– Blocking in a current-free state
– Uneven weight forces
WARNING
Danger if an axis moves in an uncontrolled manner.
There is a risk that the axis moves in an uncontrolled fashion if you release the
locking or brake in the no-current, uncontrolled state of the axis.
•
Carefully ensure that nobody is in the hazardous area.
● All cables must be routed and secured in such a way that they cannot be bent, pressed
against rotating parts or damaged in any other way.
● Coolant supply ducts must be easily accessible and the coolant must be allowed to flow
freely.
● Check the minimum air gap using a 1 mm thick foil.
Production-related clearances
When mounted, axial clearances can occur between the ends of two adjacent stator
segments, refer to the following diagram.
Figure 5-17 Production-related clearance for mounted stator segments
Axial clearances can also occur between the ends of two adjacent rotor segments.
These clearances are production-related, and do not negatively impact the motor function.
