Parker K Series - Natural Cooled Motor Operation; Flange Dimensions for Performance

46 - PVD 3674_GB_K Series_CE-November 2016.Docx
3.5. Natural cooled motor
In compliance with the IEC 60034-1 standards: the ambient air temperature shall not
be less than -15°C and more than 40°C.
K Series Kit are housed in a motor frame detailled in § 3.4.4.1 Stator
Warning: To reach the motor performances calculated, the complete
motor must thermally well connected to a aluminium flange with the
following dimensions:
- K032 : 25.4 cm×25.4 cm×0.635 cm (S=1355 cm²)
- K044 : 25.4 cm×25.4 cm×0.635 cm (S=1355 cm²)
- K064 : 25.4 cm×25.4 cm×0.635 cm (S=1355 cm²)
- K089 : 30.48 cm×30.48 cm×1.27 cm (S=2013 cm²)
- K178 : 40.64 cm×40.64 cm×2.54cm (S=3716 cm²)
Caution: the ambient air temperature shall not exceed 40°C 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.
