Problems solved by technology

[0011] According to the conventional door driving device 100 used in the conventional elevator door system 1, since the driving operation of the motor 14 is entirely dependent on the switching states of the limit switches 20a and 20b, there is a problem that it is difficult to perform smooth driving to open or close the door.
[0012] In addition, in the case of installing additional components to compensate for control accuracy, problems such as increased cost, increased energy consumption, increased number of control elements, increased difficulty in control stability, etc. are caused

Abstract

A device and a method for driving an elevator door which uses a brushless DC motor for providing sliding force.

Description

technical field [0001] The present invention relates to an apparatus and method for driving elevator doors. More particularly, the present invention relates to an apparatus and method for driving an elevator door mounted on an elevator to automatically open and close. Background technique [0002] Typically, an elevator includes an elevator car and a pair of doors at each floor landing. A door driving device for driving these doors is installed at a predetermined position of the elevator car. When the elevator car arrives at the landing of each floor, a pair of doors of the elevator car and the pair of doors of the landing are engaged with each other and are opened or closed by a door driving device installed in the elevator car. An elevator door system is defined as a device comprising the door drive described hereinafter and other mechanical or electrical elements for opening or closing the doors. [0003] refer to figure 1 , describes an example of a well known door d...
