4.6 Vibration stressing
The on-site mechanical system vibration characteristics depend on factors such as the
output elements, mounting situation, alignment, installation, and external vibration and can
increase the level of motor vibration.
Under certain circumstances, the rotor may have to be balanced completely with the output
element.
To ensure problem-free operation and a long service life, the vibration values specified to
ISO 10816 must not be exceeded at the defined measuring points on the motor.
