1.5.1 Important Notes
Only qualified staff with knowledge of mechanical engineering are permitted to
assemble the motor.
Protect the motor from unacceptable stresses. During transport and handling no components
l
must be damaged.
The site must be free of conductive and aggressive material. For V3-mounting (shaft end
l
upwards), make sure that no liquids can enter the bearings.
Ensure an unhindered ventilation of the motors and observe the permissible ambient and flange
l
temperatures. For ambient temperatures above 40°C please consult our applications department
beforehand. Ensure that there is adequate heat transfer in the surroundings and the motor
flange.
Motor flange and shaft are especially vulnerable during storage and assembly - so avoid brute
l
force. 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
l
alignment of the couplings. A displacement will cause unacceptable vibration and the destruction
of the bearings and the coupling.
In all cases, do not create a mechanically constrained motor shaft mounting by using a rigid
l
coupling with additional external bearings (e.g. in a gearbox).
Take note of the no. of motor poles and the no. of resolver poles (if applicable), and ensure that
l
the correct setting is made in the servo amplifier which is used. An incorrect setting can lead to
the destruction of the motor, especially with small motors.
Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly shortens the life
l
of the motor.
Check the compliance to the permitted radial and axial forces F
