Coolant intake temperature
Condensation can lead to corrosion in the machine.
• Select the intake temperatures so that no condensation forms on the surface of the
motor. Condensation does not form if the intake temperature T
VORL
is higher than the
ambient temperature or corresponds to the ambient temperature.
The rated motor data refer to operation at a coolant intake temperature of 35 °C. If the intake
temperature is different, the continuous motor current changes as shown below.
Note
For a cooler intake temperature of <
35 °C, the possible continuous motor current is greater
N
.
-sections may be required. This means that you must take into account
the rated current of the cables.
The following diagram shows the dependency of the relative continuous primary section
current (I
Primärteil
/ I
N
) * 100 on the water intake temperature in the cooling system. Losses due
to friction and eddy currents are ignored here.
