13 Mechanical Installation
Dimension drawings can be found in chapter "Dimension Drawings" (➜ # 73).
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
l
components must be damaged. Avoid scratches on the stainless steel surface and cuts
on the tube.
Basic styles for flange mounting according to EN 60034-7:
l
Flange mounting (flange types Ax, Bx)
Shaft end upwards mounting and cable bushing on top of motor is not allowed in hygienic
l
applications.
Use o-ring (part of delivery) for face or flange interface at motor mounting.
l
Use sealed screws for motor mounting.
l
If the shaft is exposed, cover the shaft center hole with sealed screw.
l
Mount the cable bushing in the "down" or lower hemisphere region to promote drainage
l
after washdown. Add a strain relief to the cable if necessary.
Ensure an unhindered ventilation of the motors and observe the permissible ambient and
l
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
l
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 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.
l
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
l
rigid coupling with additional external bearings (e.g. in a gearbox).
Avoid axial loads on the motor shaft, as far as possible. Axial loading significantly
l
shortens the life of the motor.
Check the compliance to the permitted radial and axial forces F
l
When you use a toothed belt drive, the minimal permitted diameter of the pinion e.g.
follows from the equation: d
allowed: B5
≥ (M
/F
)*2.
