investigations
coolants, additives, or operating conditions.
The performance test for the used coolants and the design of
the liquid coolant system are generally the responsibility of the
machine manufacturer. See also Chapter 9.4 "Compatibility".
When used with MAF motors, the coolant comes into contact with the
following materials:
Motor, housing
CU, CuZn39Pb2

MAF material
In dimensioning and operating the cooling system, the machine
manufacturer has to exclude all chemical or electro-chemical interactions
with subsequent corrosion or decomposition of motor parts.
IndraDyn A motors are designed according to DIN EN 60034-1 for
operating with +10...+40°C coolant inlet temperature. 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.
