The present invention relates to a low-speed brake apparatus for an escalator, comprising: a brake sprocket mounted on a drive shaft for a step; a driven sprocket connected to the brake sprocket through a brake chain to operate in conjunction with the brake sprocket; an electronic clutch that controls a connection between the driven sprocket and a transmission gear; a brake motor of which the central shaft is rotated by the transmission gear; a plurality of switching means connected to a plurality of winding wires that are stators of the brake motor; and a controller for supplying an operating pulse to a selected switching means. Therefore, when there is an abnormality in an escalator, it is possible to stop a step at a low speed according to an operating pulse supplied by the controller, thereby stably stopping riders standing on the step and thus protecting the riders. |
