Specifications for mounting torque motors

Mounting system
The following must be taken into account when the torque motor is mounted:
● Only use new (unused) fixing screws.
● The mounting surfaces must be free of oil and grease.
● Note the maximum permissible insertion depth of the fixing screws in the stator and rotor
(refer to the relevant installation drawing or the following table).
● Minimum insertion depth of the mounting screws in the stator:
1.0 x d + section without threads
● Minimum insertion depth of the fixing screws in the rotor flange (in steel):
1.1 x d
● To secure the screws, choose long clamping lengths l
(if l
with calibrated torque wrench).
● Note the tightening torques specified in the table below.
● Tighten the screws in such a way that the angle of rotation is controlled. Using a
calibrated torque wrench with the shortest possible bit insert, however, ensure that they
are tightened in diagonally opposite (180°) pairs.
● Tighten all the screws to minimize the risk of them penetrating other materials.
● Do not use any liquids for securing the screws.
