3.3. Motor mounting

3.3.1.

By flange

Motor mounting

By feet – for long motor a support

must be added

3.3.1.

Typical mounting.

Warning
No additional weight must be mounted on the shaft, even if this weight
generates a force lower than the maximum force allowed on the shaft.
Indeed, this weight can reduced the shaft resonance frequency and leads to
its failure.

:

The load must be supported by bearings

.

For vertical mounting, the load capacity and
vibration resistance on shaft are different than
horizontal mounting.
