An architectural covering having a drive mechanism for extending and retracting a covering member (108) between opposite first and second end positions. The drive mechanism includes an electric motor unit (31) having a stationary end (33) and a rotating end (35) for rotating a winding core, such as a roller blind shaft (106), for receiving wound layers of a flexible element, such as a sheet of flexible material (108) thereon. The drive mechanism further includes a motor head (1), separate from the electric motor unit (31), providing external electrical control for the motor unit (31) via an electrical interface. A printed circuit board (19) accommodated in the motor head (1) may include at least one of end position limit switches, a switch for setting the first and second end positions, electronic communication means, or a remote control receiver. The electrical interface may include an electrical connector plug (17; 17A), an electrical socket (37; 37A), and/or an electrical cable (55; 75). |
