Motors with integrated cooling

These motors are equipped with a ready-to-connect, integrated dual-circuit cooling system, which provides considerable thermal insulation vis-à-vis the mechanical axes 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 Pv of the stator. 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.
