3.3 Cooling
Effects when water cooling is not used
If water cooling is not used, the motor can only be loaded in continuous operation
(depending on the size, power loss, emissions area, convection, and installation conditions
in the machine) with a significantly reduced continuous torque (M << M
N
). The max. torque
M
MAX
of the motor can be fully utilized here.
WARNING
Without water cooling:
Significant reduction of continuous torque (depending on the thermal connection to the
Significant reduction of continuous torque (depending on the thermal connection to the
surrounding construction) and considerable rise in the temperature of the machine
construction.
This is why a water-cooling system is essential.
In the case of axes that are to be operated without water cooling, the reduction of the
continuous motor torque and the thermoelastic deformation of the machine construction
(warping through expansion) must be taken into account in the drive configuration and
design.
Note
Motors with integrated cooling should not be operated without water cooling.
Motors with integrated cooling should not be operated without water cooling.

Cooling circuits
Cooling circuit requirements
We recommend that the cooling circuits be designed as closed systems, to prevent the
growth of algae. The maximum permissible pressure is 10 bar.
Note
We do not recommend that the cooling circuits of machines are also used to cool the motors:
We do not recommend that the cooling circuits of machines are also used to cool the motors:
Due to accumulated dirt and long-term deposits, blockage may result! This especially applies
to cooling-lubricating medium circuits.
If the cooling circuits of the machines are also used to cool the motors, then they must fulfill
all of the requirements listed here. Also note the demands on the cooling medium as well as
the maximum standstill times of cooling circuits according to the specifications of the cooling
medium manufacturer!
