SERVOMOTOR
Radial load and axial load
A poor alignment between the motor shaft and the machine axis
increases vibration of the shaft and reduces the useful life of bearings and
couplings. Likewise, exceeding certain maximum radial load values on the
bearings has a similar effect.
Bear in mind the following considerations in order to avoid these
problems:
Use flexible couplings for direct coupling.
Avoid radial and axial loads on the motor shaft making sure that they
do not exceed the limit values.
See these values in the following chapters for each motor model.
INFORMATION.
When applying a combined axis and radial load, decrease the maximum
radial force allowed “Fr” to 70 % of the value indicated in the table.
WARNING: DO NOT hit the motor!
AC servomotors have extremely fragile optical and electronic
components. Avoid hitting the motor and especially its shaft extension
when installing transmission pulleys and gear boxes.
DO NOT
hit the
motor, especially on the shaft extension.
i
Use some tool that is supported in
the threaded hole on the shaft to
insert the pulley or the gear.
