Important notes
• The mounting surface must be dimensioned for the design, weight and torque of
the motor.
• The foot and flange faces must rest flat on the mounting surface.
– Incorrect motor alignment reduces the service life of the roller bearings and
transmission elements.
Impacts on shafts can cause bearing damage.
• Do not exceed the permissible range of ambient operating temperature ( 19).
• Fasten the motor securely.
• Ensure that the ventilation is not impeded. The exhaust air, also the exhaust air of
other machines next to the drive system, must not be taken in immediately.
• During operation, surfaces are hot, up to 140 °C! Ensure that guard preventing
accidental contact is in place!
Note!
From the air inlet to other component parts, a minimum distance of 10%
of the outer diameter of the fan cover must be complied with!
Ensure an even surface, solid foot or flange mounting and exact alignment if a direct
clutch is connected. Avoid resonances with the rotational frequency and double
mains frequency which may be caused during assembly. With an additional support
on the N-end side in the case of flange-mounted motors (in particular for MQA a nd
great MCA), vibrations that may occur can be reduced. Bracing of the motor by the
additional support must be reliably avoided.
Only mount or remove transmission elements using appropriate means. In order to
facilitate handling, heat them beforehand. Cover belt pulleys and clutches with a touch
guard.
Stop!
Ensure a correct belt tension!
The machines are halfkey balanced. The clutch must be halfkey balanced, too. The
visible jutting out part of the key must be removed.
Designs with shaft end at the bottom must be protected with a cover at the N-end,
preventing the ingress of foreign particles into the fan.
