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).
● The minimum insertion depth for the fixing screws in the stator:
1.0 x d + section without threads (valid for 1FW605 and 1FW606)
1.3 x d (valid for 1FW609 to 1FW613)
1.0 x d (valid for 1FW615 and higher)
● Minimum insertion depth of the fixing screws in the rotor flange (in steel):
1.1 x d (valid for 1FW605 and 1FW606)
1.0 x d (valid for 1FW609 to 1FW629)
● To secure the screws, choose long clamping lengths l
k
, l
k
/ d > 5 if possible; alternatively
(if l
k
/ d > 5 is not possible), check pretensioning of the screws at regular intervals (tighten
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.
Explanations:
I
k
= Clamping length of the screw in mm
d = Nominal diameter of the screw in mm (e.g. M8 screw: d = 8 mm)
