Electrically actuated motorized shutter driving device, has studs transformed into other studs by rotating former studs to specific degree around axis passing through center of plug and parallel to coupling direction
The device has a motor e.g. asynchronous motor, comprising an interface with connection terminals, where excitation of each terminal drives the motor along rotational directions. A plug (5) has studs (51-54) extending along a coupling direction, where the studs (51, 52) are connected to the terminals, and the studs (53, 54) are connected to a third terminal, where the studs (51-54) form keying elements. The studs (51, 53) are transformed into the studs (52, 54) by rotating the studs (51, 53) to 180 degree around an axis (A) passing via a center of the plug and parallel to the direction. An independent claim is also included for a device for supplying and controlling a shutter motor comprising a supply interface.
