Motorized damper :
The quantity of air exhausted is controlled by the servomotor.
The fast servomotor (8s for 90°) is mounted directly on the
damper axis show a 8Nm couple (see picture opposite).
The servomotor is controlled directly by the Ecro, this guarantees
a stability and accuracy. For the fumehoods, we use dampers
with diameters of 200 mm or 250 mm.

The motor part.
The servomotor has been
chosen from the proportional
range of the brand Joventa, its
reference is SM1.2.
Applications: this range of elec
-
trical servomotors has been
designed for air dampers in
HVAC applications (Heating, Ventilation and Air-Conditioning).
Joventa’s universal adapter is particularly
convenient. It allows a rotation angle limitation with a position
indicator.
Specifications : command …10V cc or 0…20 mA – Running
time independent from the load – Possibility of having 5
servomotors functioning in parallel- Plug-in screw terminal
blocks – Universal adapter for a cylindrical axis 10 to 20 mm ø,
for a square axis 10 to 16 mm on the side.
The axis must be 48 mm long minimum – turning direction
selectable – rotation angle limitable – manual control possible
by disengaging the push-button – 2 auxiliary adjustable po-
tential-free contacts optional (.S) – End auto-stop (overload
protection) – Energy consumption reduced at the limit.
