The invention belongs to the technical field of motor braking, and discloses a motor braking protection device which comprises a fixing frame, armatures, spring telescopic rods and an output shaft, the armatures are fixedly connected to the left side and the right side of the top of the fixing frame, and the spring telescopic rods are fixedly connected to the left side and the right side of the middle of the fixing frame. The other side of the armature is fixedly connected with a pull rod, and the other side of the pull rod is hinged to a movable column. Through structural cooperation of a limiting ring, a movable ring, a first spring, a friction block, a limiting pipe and the like, the damping effect of the device is good, an armature is powered off, a movable column drives the limiting ring, due to the fact that the initial rotating speed of a brake wheel is high, a third spring is bent, and the limiting pipe can be inserted into a limiting groove through a spring telescopic rod; the movable ring drives the
