The rotor is dynamically balanced. The balancing quality corresponds to vibration severity
grade "A" for the complete machine as standard. The optional vibration severity grade "B" is
indicated on the rating plate.
The declaration regarding the type of featherkey for balancing is generally marked on the
rating plate and optionally on the face of the shaft end.
Designation:
● As a standard measure, balancing is carried out dynamically with a half featherkey (code
● "F" means balancing with a whole featherkey (optional version).
● "N" means balancing without a featherkey (optional version).
The featherkey data on the shaft and transmission element must indicate the correct type of
balancing in each case and must be correctly mounted.
The balancing quality corresponds to vibration severity grade "A" for the complete machine;
vibration severity grade "B" is possible as an option, i.e. in order to ensure the desired
balancing quality, it must be ensured that the featherkey data on the hub and machine shaft
complement each other in the case of a shorter or longer output transmission element.
Measures conforming to ISO 10816 must be taken in order to compensate any offset
between electrical machines and driven machines.
The foundation must be designed according to DIN 4024.
