Title:
ELEVATOR AND CONTROL DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2017/141314
Kind Code:
A1
Abstract:
Provided is an elevator control device that allows maximum use of braking torque by reducing the resistance value of a circuit that short circuits during emergency stop and that allows easy operation during brake release. The elevator control device is provided with: a manual short circuit unit (second short circuit unit) (7) that uses braking torque obtained by three-phase short circuiting the coil of a winding motor 1 in order to prevent acceleration during rescue operations due to brake release; a manual short circuit terminal (7A) of the manual short circuit unit (7) that is in in a hall indicator box (9) installed on a floor landing and that short circuits by way of a short circuit connector (6); and an automatic short circuit unit (first short circuit unit) (5) that is in a control panel (8) housing the control device and that generates braking torque by three-phase short circuiting the coil of the winding motor (1) during emergency stop.
