For shaft mounting, the motor weight is solely carried by the shaft extension of the driven
machine.
The mounting to the motor frame cannot accept any cantilever forces and therefore does not
support the motor.
● Adequately dimension the shaft extension and the machine bearings.
The natural bending frequency can be shifted as a result of the lower stiffness of the
mounting to the motor frame.
● Avoid operating with a rotational frequency in the range of the natural bending frequency.
