If you cannot determine the actual rms power loss P
V
then alternatively you can add the
rated power losses P
V,N
of all the motors to be used. The rated power losses P
V,N
of the
motors are listed in the data sheets. Dimension the cooling system based on the sum of the
rated power losses determined P
V,N
.
If the sum of the rated power losses P
V,N
is greater than the actual rms power loss P
V
, then
this will lead to an overdimensioning of the cooling system.
The cooling system must be sufficiently powerful to ensure the required coolant pressure
even at the maximum volume flow rate.
3.1.2
Coolant
Provision of the coolant
The customer must provide the coolant. The motors are designed for use with an anti-
corrosion protection agent added to the water.
Note
Power derating when using oil as coolant
If you are using oil as coolant, then this can reduce the power loss dissipated by the cooler.
Appropriately reduce the motor power. Please contact your local Siemens office if you have
any questions.
Reason for the use of water with an anti-corrosion agent
The use of untreated water may lead to considerable damage and malfunctions due to water
hardness deposits, the formation of algae and slime, as well as corrosion, for example:
● Worsening of the heat transfer
● Higher pressure losses due to reductions in cross-sectional area
● Blockage of nozzles, valves, heat exchangers and cooling ducts
