Shutter can be:
(1)light blocking device on window (百葉窗; 活動遮板)
(2)a device in camera to let light in (快門)
(3)a blocking device in an air-duct, sometimes it is called damper (
(4)in an organ (風琴) to control air-flow.
the item (2) and (4) usually has NO motor to control its opening or closing. However, items (1) and (3) can be motorized. In this case, this motor is called "shutter motor" (阻風門馬達, or 電動百葉窗或活動遮板馬達).
If you get this terminology from a HVAC (heating, venting, air-conditioning) system, then it is likely to be 阻風門馬達. It is used to control the air flow through the entire system, it is usually integrated and controlled through computer and sensors.
