Siemens SIMOTICS T-1FW6 - Motors with Integrated Cooling

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.

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.
