Title:
ELECTROMAGNETIC BRAKE FOR PASSENGER CONVEYOR AND PASSENGER CONVEYOR WITH USE THEREOF
Document Type and Number:
Japanese Patent JP2017206341
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic brake for a passenger conveyor so that a stop distance can be shortened during emergency stop even when a brake shoe material and others of the electromagnetic brake is abraded; and to provide the passenger conveyor with use thereof.SOLUTION: An electromagnetic brake for a passenger conveyor includes: a brake coil 76; a normal circuit 78 where a first switch 82, which becomes in an ON state during normal stop, or during emergency stop when a stop distance of a footstep 30 becomes within an allowable stop distance, and a first resistance element 84 are connected in series to each other; an emergency circuit 80 where a second switch 86, which becomes in the ON state during emergency stop when the stop distance of the footstep 30 is longer than the allowable stop distance, and a second resistance element 88 are connected in series to each other; a DC power supply; and a main switch 90 that connects the DC power supply and the brake coil 76, and which becomes in the ON state during an operation state. A first resistance value R1 of the first resistance element 84 is smaller than a second resistance value R2 of the second resistance element 88.SELECTED DRAWING: Figure 3
