13.1 Important Notes
Only qualified staff with knowledge of mechanical engineering are permitted to assemble
the motor.
— Protect motor and cable from unacceptable stresses. During transport and handling
no components must be damaged. Avoid scratches on the stainless steel surface.
— Shaft end upwards mounting is not allowed in hygienic applications.
— Use o-ring for face or flange interface at motor mounting.
— Use sealed screws for motor mounting.
— If the shaft is exposed, cover the shaft center hole with sealed screw.
— Mount the cable exit in the “down” or lower hemisphere region to promote drainage
after washdown. Add a strain relief to the cable if necessary.
— 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. 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 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 compo-
nents, 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.
— 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 feedback type, and ensure that the cor-
rect setting is made in the used drive. 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 of the motor.
— Check the compliance to the permitted radial and axial forces F
