<p>PROBLEM TO BE SOLVED: To provide an emergency stop brake device capable of being automatically operated in the abnormality of an electric system. SOLUTION: This device comprises a disc brake 20 for applying the braking to a motor, a spring 64 for applying the energization force for bringing this disc brake 20 into an operating state, and the rotary solenoids 51, 52 for applying the driving force for bringing the disc brake 20 into an opened state. In a normal condition, the rotary solenoids 51, 52 are driven to open the disc brake 20 against the energization force by the spring 64, and the rotary solenoids 51, 52 are switched off in the generation of the abnormality in an electric system for operating the disc brake 20 by the energization force of the spring 64.</p> |
