The invention relates to a motor stalling protection device and a drive-by-wire hydraulic braking system comprising the motor stalling protection device, and belongs to the technical field of vehicles. The motor stalling protection device comprises an input shaft, a driving disc, an output shaft, a driven disc, a shell and a magnet exciting coil, the input shaft is fixedly connected with the driving disc, and the output shaft is fixedly connected with the driven disc; the input shaft and the output shaft penetrate through the shell, the driving disc and the driven disc are arranged in the shell, and the driving disc does not make contact with the driven disc. A cavity is formed among the shell, the driving disc and the driven disc, and magnetorheological fluid is arranged in the cavity; and the magnet exciting coil is arranged in the shell. By the adoption of the method, the risk of high-temperature burnout of the motor can be effectively reduced, and the reliability of the drive-by-wire hydraulic braking system is improved.
