The embodiment of the invention discloses an ultrasonic motor, an electronic mechanical braking system and an automobile, relates to the technical field of braking, and solves the problem that an existing electronic mechanical braking system is complex in structure. The ultrasonic motor comprises an output shaft, one or more pressing pieces arranged on the output shaft and a plurality of stator-rotor pairs. Each stator-rotor pair includes opposed ultrasonic vibrational excitation stators and rotors. And the ultrasonic oscillator excitation stators and rotors in the plurality of stator-rotor pairs are arranged on the output shaft. And the plurality of stator-rotor pairs are distributed on the output shaft at intervals. And the ultrasonic vibration excitation stators in two adjacent stator-rotor pairs are arranged close to each other and are respectively pressed on the corresponding rotors through the same pressing piece. The electronic mechanical brake system adopting the ultrasonic motor has the characteristics of large torque, low rotating speed and power-off deadlock, a speed reducing and distance increasing mechanism and a mechanical self-locking mechanism are not arranged, and the structure of the electronic mechanical brake system is simplified.
