The invention discloses a multi-shaft piezoelectric micro motor comprising a stator, rotors and output shafts. The stator comprises a part made of a piezoelectric material, an excitation signal used for driving the multi-shaft piezoelectric micro motor excites compound vibration of vertical vibration and flexural vibration on the stator, and therefore the stator drives the rotors to rotate, no less than two rotors are arranged, no less than two output shafts are arranged, and the at least two output shafts are respectively connected with the at least two rotors in order to output the rotating torque of the at least two rotors at the same time. The multi-shaft piezoelectric micro motor is advantaged by being compact in structure, large in output torque, low in cost, high in precision and simple to manufacture, having a power-failure self-locking function and the like, and the multi-shaft piezoelectric micro motor is benefit for miniaturization, industrialization and integrated installation, and has wide application prospects in biological, medical, micro mechanical, automatic control and optics lens fields and the like.
