Type of construction without flange

If the motor is not fitted with a flange, align the motor to suit the driven machine.
For types of construction without flange (e.g. IM B3), use suitable covers to ensure that no
small parts can fall down between the transmission element and the bearing shield on the
drive side.
5.5.3

Removing the rotor shipping brace

If a rotor shipping brace is attached to the machine, remove it at the last possible moment,
for example, when you are ready to push on the output or drive element.
Storing the rotor locking device
Store the rotor locking device in a safe place. It must be remounted if the machine is removed
and shipped on further.
5.5.4

Recommended alignment accuracy

The alignment accuracy required depends essentially on the configuration of the overall
machine train. Observe the required alignment accuracy of the coupling manufacturer in all
cases when aligning the machine.
