Used Materials
In IndraDyn T motors, the coolant comes into contact with the following
materials:
• AlSi5Mg (cooling jacket)
• Fluoric-rubber FPM (O-ring)
Coolant Inlet Temperature
IndraDyn T motors are designed according to DIN EN 60034-1 for
operation with a coolant temperature between +10 and +40°C. This
temperature range must be strictly observed. At higher coolant
temperatures, the reduction of the available torque is increased. Because
of high coolant temperature gradients, lower temperatures can lead to
destruction of the motor.
Note: Install systems in the cooling circuit for monitoring flow,
pressure and temperature.
Observe the permitted temperature range and heed the existing ambient
temperature when setting the coolant inlet temperature. The lower limit of
the recommended coolant inlet temperature can be limited compared to
the existing ambient temperature. To avoid condensation, a value of max.
5°C below the existing ambient temperature is permitted as the lowest
temperature to be set.
Example 1:
Specified temperature range: +10 - +40°C
Ambient temperature: +23°C
Set coolant inlet temperature: +18 - +40°C
Example 2:
Specified temperature range: +10 - +40°C
Ambient temperature: +32°C
Set coolant inlet temperature: +27 - +40°C
