3.4.1.3 Motors with integrated cooling
Motors with integrated single-circuit cooling
These motors have an integrated single-circuit cooling system that is ready to be connected.
Further, they are compact, and can therefore be simply integrated into a machine.
① Stator with integrated cooling
② Rotor with permanent magnets
③ Transport lock
④ Electrical connections
⑤ Cooler connection

Motors with integrated dual-circuit cooling
These motors are equipped with a ready-to-connect, integrated dual-circuit cooling system,
which provides considerable thermal insulation with respect to the mechanical axis
construction.
The dual-circuit cooling system comprises a main and precision cooler
(thermo-sandwich® principle).
An internal cooling circuit (main cooler) dissipates most of the winding losses P
v
of the
stator. A thermal insulation layer between the stator and the mounting anges of the stator
prevents heat from owing from the motor winding to the machine construction.
Any heat that does ow through the insulation layer is captured, for the most part, by
a second heat sink (precision cooler) on the ange surfaces and dissipated. This ensures
that the temperature on the mounting surfaces of the stator remains suitably low under all
permissible operating conditions.
