Servomotors AKM
06/2010
Protect the motor from unacceptable stresses.
Take care, especially during transport and handling, that components are not bent and that
insulation clearances are not altered.
The site must be free of conductive and aggressive material. For V3-mounting (shaft end up-
wards), make sure that no liquids can enter the bearings. If an encapsulated assembly is re-
quired, please consult our applications department beforehand.
Ensure an unhindered ventilation of the motors and observe the permissible ambient and
flange temperatures. For ambient temperatures above 40°C please consult our applications
department beforehand.
Servomotors are precision equipment. The flange and shaft are especially vulnerable during
storage and assembly — so avoid brute force. Precision requires delicacy. It is important to
use the locking thread which is provided to tighten up couplings, gear wheels or pulley
wheels and warm up the drive components, where possible. Blows or the use of force will
lead to damage to the bearings and the shaft.
Wherever possible, use only backlash-free, frictionally-locking collets or couplings. Ensure
correct alignment of the couplings. A displacement will cause unacceptable vibration and the
destruction of the bearings and the coupling.
For toothed belts, it is vital to observe the permissible radial forces. An excessive radial load
on the shaft will significantly shorten the life of the motor.
Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly shortens
the life of the motor.
In all cases, do not create a mechanically constrained motor shaft mounting by using a rigid
coupling with additional external bearings (e.g. in a gearbox).
Take note of the no. of motor poles and the no. of resolver poles, and ensure that the correct
setting is made in the servo amplifier which is used. An incorrect setting can lead to the de-
struction of the motor, especially with small motors.
