Furthermore the loading case of the force F

has to be taken into consideration:

The position of the motor‘s centre of gravity, including all motor options, must be
calculated. If the distance of the centre of gravity L
Tab
is greater, the permissible force
must be reduced as follows.
U = k x F x k x F

If forces act from several directions, e.g. in the case of a moving horizontal travelling
drive, the acting forces have to be added vectorially (e.g. vertical force due to weight plus
horizontal acceleration force).

corresponds to the maximum value of the forces added vectorially!

If the permissible force F
Mperm
is exceeded, the motor has to be supported in a suitable,
distortion−free fashion!
