3.1.2.2. Water cooled motor
Typical values are given with a water inlet temperature of 25°C and a temperature
gradient Inlet-Outlet of 10°C. These references lead to a winding overheating of 95°C
corresponding to a winding temperature of 120°C. Recommendations regarding
condensation issues are given at § 3.5
It is possible to increase a little bit the Inlet temperature up to 45°C, but the torque
must be reduced. The following curves give an indicative of the derating versus the
speed for different temperature.
