Flange mounting
The flange is only used to transfer the torque. Due to the empty weight or as a result of
vibrations that arise if the flange is too soft, the motor can be damaged if it is only fastened via
the flange.
1. Fasten the flange-mounted motors via a stable motor suspension and support them via the
end shield feet (foot flange type of construction).
2. During commissioning, ensure that the permitted vibration values are maintained in
accordance with ISO 10816‑3.
If the motor is to be only flange mounted, then the maximum speed n

is reduced for rigid
foundations according to the following table:
