The invention provides a giant magnetostrictive material-based rocking head type micromotor, which comprises a stator, a rotor and a precompression system, wherein the stator comprises a magnetic deformation body and a metal base body; a magnetostrictor body extends along the magnetization direction under the action of the applied magnetic field; two first-order bending vibration modes with a certain included angle in space are excited on the stator; the motion track of a mass point on a contact drive end surface of the stator and the rotor is an ellipse; the rotor runs through the hollow stator and is pressed on a drive end of the stator under the action of the precompression system; and the stator drives the rotor to rotate through friction. According to the giant magnetostrictive material-based rocking head type micromotor, wireless driving is achieved by external magnetic field excitation; microminiaturization is easy to achieve; and a piezoelectric material body is used for monitoring the running state of the motor in real time, and can also be used as a magnetoelectric conversion unit for achieving wireless energy supply and the like. The giant magnetostrictive material-based rocking head type micromotor is especially suitable for the occasions, such as the fields of medical diagnosis, robots and the like, which require accurate positioning.
