Specifications for integration in the machine

Fits for motors with integratedcooling
Built-in torque motor stators with integrated cooling have a centering collar at both flanges. In
the factory, the centering collars are machined with tolerance class f8 with respect to the
nominal dimensions. The outer diameter is always slightly below the nominal dimension.
Tolerance class H8 is recommended for the centering collar on the customer side in which
you wish to insert the stator. The centering collar diameter always has its nominal dimension
or is slightly larger.
For motors with integrated cooling, a centering collar on the machine side as mating surface
to the centering collar on the motor side is sufficient.
You may only insert motors with integrated cooling with the mounting flange in a centering
collar.
It is not necessary to install the stator in a machine bore (enclosure).
However, if you do install the stator in a machine bore, then you must maintain a gap of
at least 1.5 mm around the complete circumference to allow for thermal expansion of the
stator, and more specifically:
• over the complete peripheral surface of the stator
• At the free flange
