[QUOTE="Ampdog, post: 42329, member: 144"] I also did not have a look here lately. AC/DC motors have roughtly the same torque if they are of the field-coil-armature-coil type (i.e. with brushes). They can reach quite a speed also - higher gearing, greater power. It is the a.c. induction motors that have less power; v.v. bigger motor for the same torque. Can't the screen swing up against the ceiling - distances wrong, I suppose. Or hoist it up from low vertical position behind something, taking cables over pulleys at uppermost position down to motors below, covering the cables with something artful? Making a scissors or similar seems quite an undertaking. [/QUOTE]
