Motor Description
1.7 Cooling
Cooling system
A cooling system (i.e. heat exchanger) must be used in order to guarantee a cooling medium
intake temperature of +30°C. It is possible to operate several motors from a single cooling
system. The cooling system is not included in the scope of supply.
Cooling system manufacturer, refer to the Catalog.
The cooling power is calculated from the sum of the power losses of the connected motors.
The power of the pump and the distribution to different cooling circuits should be engineered
corresponding to the specified flow and the pressure losses of the individual cooling circuits.
If one pump is used with distribution to several cooling circuits, then it may be necessary to
use a flow controller.
