Beschreibung
Zusammenfassung:	FIELD: drive or working unit intended for displacement of the lift cabin doors during the opening and closing cycles of lift operation. SUBSTANCE: lift door or doors are actuated during the opening and closing cycles by means of one or more units of a line-fed induction motor, in which the stator winding member of the induction motor unit is attached to the lift cabin construction, and the rotor winding, member of the induction motor is attached to the cabin door. If the cabin has two doors moving in opposite directions, it is preferable to have two separate drives from the motor, one for each door. In one variant the motor members are arranged in such a manner that they produce a normal force, which is horizontal; in another variant the produced normal force is vertical. The bracket for mounting the motor stator winding is used, it fastens the stator winding member to the upper member of the cabin construction. EFFECT: improved design. 31 cl, 7 dwgi
