Vibrations, balancing
Motors with a keyway are balanced by the manufacturer with a half feather key.
The site vibration response of the system is determined by the output elements, the
mounting conditions, the alignment, the installation and the effects of external vibrations.
This may cause a modification of the motor vibration values.
Output elements
Do not strike the shaft or bearings of the motors.
Do not exceed the permissible axial and radial forces on the shaft end stated
in the configuration specification.
Axial forces are not permitted on motors with an integrated brake.
Suitable devices should always be used to push on or pull off the output elements (e.g. the
coupler, gear wheel, belt pulley, Fig. 4).
-
Use the tapped hole in the shaft end.
-
Heat up the output elements if necessary.
-
Use a shim to protect the centering in the shaft end when pulling output elements off.
-
If necessary, fully balance the motor with the output elements according to ISO1940
