Motor Description
1.7 Cooling
1.7.3
Water-cooling
The power loss generated by the motor is dissipated using a water cooling system. The
machinery construction company must connect-up a cooling system (e.g. heat exchanger).
The rated motor torques, specified in the motor data sheets apply for water-cooled operation
and a water intake temperature of < 30 °C.
Notice
If the motor is operated without water cooling, then the rated motor torque is reduced as a
function of the heat losses which can be dissipated by convection and radiation. In this case,
the data for non-ventilated operation apply.
Note
It is not possible to retrofit a motor for water cooling.
The cooling medium must be pre-cleaned and filtered in order to prevent the cooling circuit
from becoming blocked. The maximum permissible particle size after filtering is 100 mm.
Cooling circuit
Notice
If current is flowing through the motor, then the cooling circuit must be activated.
