The invention relates to a power-off disc type double-braking brake, and relates to the technical field of elevator brakes. The static friction disc is fixed on a shell of the traction machine, a movable friction disc is connected to a shaft in a sliding mode, an installation shell is fixed on the shell, the shaft of the traction machine sequentially penetrates through the static friction disc, the movable friction disc and the installation shell, an installation groove is formed in the installation shell, and an armature is inserted in the installation groove. The armature can move in the mounting groove in the direction close to or away from the shell, a plurality of mounting holes are formed in the side, away from the shell, of the mounting groove, electromagnets are inserted into the mounting holes, propelling springs are fixed to the two ends of each electromagnet, a plurality of magnet exciting coils are fixed in the mounting shell, and the magnet exciting coils are radially distributed with the center of the mounting shell as the center. According to the invention, the effect of larger and more stable magnetic force can be achieved by applying the same current.
