Motors with integrated cooling

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 according to the
Thermo-Sandwich® principle.
An internal cooling circuit (main cooler) dissipates most of the winding losses P
A thermal insulation layer between the stator and the mounting flanges of the stator prevents
heat from flowing from the motor winding to the machine construction.
Any heat that does flow through the insulation layer is captured, for the most part, by a
second heat sink (precision cooler) on the flange surfaces and dissipated. This ensures that
the temperature on the mounting surfaces of the stator remains suitably low under all
permissible operating conditions.
