Abstract (en)
[origin: WO9804801A1] Door drive functioning by means of a friction wheel, for a sliding door for elevators, consisting of at least one door leaf (1) moving in a linear or curving motion that is suspended by means of guide rollers (3) and guided along a guideway (2). At least one of the guide rollers (3) is designed as a motorized roller (3') moving the door leaf, in the form of an external-rotor motor. The motor is either a direct-current motor with permanent magnets (5) in the external rotor, and electronic commutation, or a three-phase alternating-current motor with laminated external rotor with short-circuited winding and laminated internal stator (6) with three-phase winding. In addition, a power transmission element (18) can be provided between the motorized roller (3') and the guide roller (3") if needed.
