3.8 Balancing
The motors are balanced according to EN 60034-14.
Motors with feather key in the shaft are half-key balanced.
A mass equalization for the protruding half key must be taken into account for the output
elements.
3.9 Vibrational behavior
Vibration severity grade
Motors with a keyway are balanced with a half feather key by the manufacturer.
The vibration response of the system at the location of use is influenced by output elements,
any built-on parts, the alignment, the installation, and external vibrations. This can change
the vibration values of the motor.
The motors conform to vibration severity grade A according to EN 60034-14 (IEC 60034-14).
The specified values refer only to the motor. The conditions at the installation location can
influence the system vibration response and increase the vibration values on the motor.
The vibration severity grade is maintained up to the rated speed (
n
N
).
