3.6. Cooling
In compliance with the IEC 60034-1 standards:
The ambient air temperature shall not be less than
-20°C
and more than
40°C.
It is possible to use the motors in an higher ambient temperature
between
40°C
to
60°C
but with an associated derating to the motor
performances (see motor characteristics §3.2)
Warning: To reach the motor performances calculated, the motor
must be thermally well connected to a aluminium flange with a
dimension of 400 mm x 400 mm and with a thickness of 12 mm.
Caution: the ambient air temperature shall not exceed 40°C
(respectively 60°C with associated derating) in the vicinity of the
motor flange
Warning: A significant part of the heat produced by the motor is
evacuated through the flange.
•
if the air is not able to circulate freely around the motor,
•
if the motor is mounted on a surface that dissipates not well the
heating (surface with little dimensions for instance),
•
if the motor is thermally isolated,
•
if the motor is mounted on a warm surface (mounted on a gearbox
for instance),
then the motor has to be used at a torque less than the rated torque.
