NOTICE
Damage to the motor due to runout on the shaft extension
Runout and thrust on the shaft extension of the motor can damage the motor.
● Mount the motor without runout and thrust on the shaft extension.
Mount or remove the power output elements (e.g. couplings, gear wheels, belt pulleys) using
suitable devices only (see figure).
● Use the threaded hole in the shaft extension.
● If required, heat up the output elements before mounting or removing.
● When removing the output elements, use an intermediate disk to protect the centering in
the shaft extension.
● If necessary, completely balance the motor together with the output elements according to
ISO 1940.
Note
Motors with feather key are half-key balanced. The motors have been balanced with half
a feather key.
