Cooling system<br />

Motor Description<br />

1.7 Cooling<br />

A cooling system (i.e. heat exchanger) must be used in order to guarantee a cooling medium<br />

intake temperature of +30°C. It is possible to operate several motors from a single cooling<br />

system. The cooling system is not included in the scope of supply.<br />

Cooling system manufacturer, refer to the Catalog.<br />

The cooling power is calculated from the sum of the power losses of the connected motors.<br />

The power of the pump and the distribution to different cooling circuits should be engineered<br />

corresponding to the specified flow and the pressure losses of the individual cooling circuits.<br />

If one pump is used with distribution to several cooling circuits, then it may be necessary to<br />

use a flow controller.<br />
