corrosion and cavitation. An oil content of 0.5 – 2 volume percent has
proven itself.
If the corrosion protection oil is responsible for not only corrosion
protection but also lubricating the coolant pump, an oil content of 5
volume percent is necessary.

Coolant Inlet Temperature
IndraDyn H motors are designed according to DIN EN 60034-1 for
operating with a coolant temperature between +10...+40°C. This
temperature range must absolutely be maintained. At higher coolant
temperatures, the available torque is reduced more and more. Lower
coolant temperatures can lead to destruction of the motor because of
high temperature gradients.
Note: Install systems in the cooling circuit for monitoring flow,
pressure, and temperature.
The coolant inlet temperature must be set taking into account the
specified temperature range and the existing ambient temperature.
If necessary, the minimum recommended coolant inlet temperature can
be limited depending on the existing ambient temperature. To prevent
condensation, a temperature of max. 5°C below the existing ambient
temperature is permitted as the lowest value that can be set.
Example 1:
Permissible coolant inlet temperature range: +10 ... +40°C
Ambient temperature: 20°C
Coolant inlet temperature to be set: +15 ... +40°C
Example 2:
Permissible coolant inlet temperature range: +10 ... +40°C
Ambient temperature: 30°C
Coolant inlet temperature to be set: +25 ... +40°C
