Elevator cab door drive system. |
摘要 |
<p>The door 2 or doors on an elevator cab are driven during their opening and closing cycles by a linear induction motor drive system 18. The primary 20 of the linear motor is fixed to the cab assembly, and the secondary 22 is mounted on the door hanger panel 4 and moves with the door. In order for the secondary 22 to maintain a proper spacing relative to the primary 20, a flexible connection 24 is provided between the secondary and the remainder of the door. In this way, shifting of the door 2 during its opening and closing movements will not cause misalignment of the secondary 22 with respect to the primary 20. <IMAGE></p> |
