Installation tolerances
Mechanical Installation
•
Protect the components from mechanical damage.
•
Only install the gearmotor in the specified mounting position on a level, vibration-free
and torsionally rigid support structure.
•
Align the motor and the driven machine carefully in order to prevent the output shaft
from being exposed to unacceptable strain. Observe the permitted overhung and
axial forces.
•
Provide for sufficient clearance around the motor to allow for adequate cooling.
•
Heat is dissipated (cooling) also via the primary flanges on the output shaft end. To
achieve the rated power, the mounting surface must be dimensioned so that the heat
can be dissipated.
•
Make sure that the warm exhaust air of other devices is not sucked in.
•
For shafts with keyway: Balance components for subsequent mounting on the shaft
with a half key (motor shafts are balanced with a half key).
4.4.1
Installation in damp locations or in the open
•
Try to arrange the motor and encoder connection so that the connector cables do not
point upwards.
•
Clean the sealing surfaces of the connector (motor or encoder connection) before re-
assembly.
•
Replace any brittle seals.
•
If necessary, restore the anticorrosive paint coat.
•
Check that the degree of protection is maintained.
•
If necessary, attach covers (protection canopy).
