3.3 Cooling
In this case, the resulting discrepancy vis-à-vis the actual effective power loss may mean
that the cooling system is overdimensioned.
The cooling system must be sufficiently powerful to ensure the required coolant pressure
The cooling system must be sufficiently powerful to ensure the required coolant pressure
even at the maximum volume flow rate.

Coolant
Provision of the cooling medium
The customer must provide the cooling medium. Only water with anti-corrosion agent should
be used as the cooling medium.
WARNING
Oil must not be used as a coolant because it is incompatible with materials used in motors
with a cooling jacket and may cause O-rings to corrode. In motors with integrated cooling,
oil can corrode the hoses of the cooling system inside the motor.
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
For this reason, water as a cooling medium must contain an anti-corrosion agent that reliably
● Worsening of the heat transfer
● Higher pressure losses due to reductions in cross-sectional area
● Blockage of nozzles, valves, heat exchangers and cooling ducts
For this reason, water as a cooling medium must contain an anti-corrosion agent that reliably
prevents deposits and corrosion even under extreme conditions.
General requirements placed on the cooling medium
The cooling medium must be pre-cleaned or filtered in order to prevent the cooling circuit
from becoming blocked. The formation of ice is not permitted!
Note
The maximum permissible size for particles in the cooling medium is 100 μm.
