MBT Synchronous Torque Motors
●
In general, the stator has to be connected to the machine via
all mounting holes.
●
All screwed connections are equipped with a liquid screw
lock. See also
●
The necessary screw length for fastening the stator depends
on the machine construction.
●
The screwed connections has to be able to take up both the
force due to the weight of the motor and the forces acting
during operation.
1. Lift and position the stator on the machine via suitable lifting tools and
the lifting eyebolts.
Avoid...
●
jamming or clamping the housing while mounting it to the
machine.
●
damaging the centering collar on the housing and the ma‐
chine.
2. Center the stator housing on the machine using the centering collar pro‐
vided on the housing. Because of the enormous torque development of
the motors, all of the mounting holes on the motor flange must always
be used to fasten the motor. An exception are frame sizes 530B, 530C
and 530E where at least the two outer mounting holes must be used per
quarter hole circle diameter on the motor flange. Use screws with prop‐
erty class 8.8 or higher.
The property class of the screws and the hardness category of
the washers has to be equivalent in order to transmit the required
tightening torques (see

3. Check the correct position of the stator and tighten all mounting screws
crosswise to the required tightening torque.
