3.6. Cooling
In compliance with the IEC 60034-1 standards:
3.6.1.
Natural cooled motor
– TMA series
The ambient air temperature shall not be less than
-15°C
and more than
40°C.
3.6.2.
Water cooled motor
– TMW series
Danger: The cooling system has to be operational when the motor is
running or energized.
Danger: The Inlet temperature and the water flow have to be monitored
to avoid any exceeding values.
Caution: When motor is not running, the cooling system has to be
stopped 10 minutes after motor shut down.
Caution: Condensation and risk of rust may occur when the
temperature gradient between the air and the water becomes
significant. Condensation is also linked to hygrometry rate.
To avoid any issue, we recommend: T
water
> T
air
- 2°C.
The motor can be used with an ambient temperature between 27°C to
40°C with a high water temperature but with derating.
If inlet water temperature becomes higher than 25°C, derating factor
must be applied according to §3.1.2 Temperature Derating
Caution: the ambient air temperature shall not exceed 40°C in the
vicinity of the motor flange
Danger: If the water flow stops, the motor can be damaged or
destroyed causing accidents.
