Problems solved by technology

However, the doorstep clearance may still be large for the obvious reason that the elevator car should be able to move smoothly in the elevator shaft without contacting any surrounding structure that would cause noise and damage to the equipment. Big

Embodiment Construction

[0042] figure 1 An elevator 100 according to an embodiment of the invention is schematically shown by means of a cross-sectional side view. Elevator 100 may include an elevator shaft 102 and an electric linear motor 125 coupled to elevator car 110 . Electric linear motor 125 is configured to move elevator car 110 in elevator hoistway 102 . Elevator 100 may preferably include at least two landing levels including landing doors 120 and / or openings 120 .

[0043] Elevator car 110 may preferably be designed to serve a landing level during normal operation of elevator 100 . Movement of elevator car 110 may generally be upward and downward. However, the electric linear motor 125 may also be arranged to move the elevator car 110 in a horizontal direction or in any other direction. This can be achieved by arranging one or more stator beams 130 to be aligned with respect to a desired direction. The stator beam 130 may comprise one or more stators 140, or may be substantially the s...

Abstract

A method and an elevator control unit (1000) for controlling a doorstep gap (11) at a landing floor of an elevator (100) and an elevator (100) are presented. The elevator (100) comprising an electriclinear motor (125) coupled to an elevator car (110), wherein the method comprises moving (72) the elevator car relative to a stator beam (130) of the electric linear motor at the landing floor for controlling the doorstep gap (11) at the landing floor.

Description

technical field [0001] The present invention generally relates to the technical field of elevators. However, the invention in particular does not only relate to elevators comprising electric linear motors, but also to controlling the movement of the elevator car of such elevators at landing levels. Background technique [0002] The elevator car of a conventional elevator is configured to move within the elevator shaft or hoistway by means of hoisting ropes attached to the elevator car. Furthermore, the hoisting ropes are connected to a hoisting motor, which can be arranged, for example, at the top of the elevator shaft. [0003] Currently, elevators utilizing electric linear motors are being developed. The motion of the elevator car may be produced by one or more movers associated with the stator of the electric linear motor. The stator is arranged in a fixed manner relative to the environment, ie the elevator shaft. [0004] The use of electric linear motors in elevator...
