Multi-degree-of-freedom (DOF) motors have become more and more useful in the complex electromechanical system. Multi-DOF motor composed of plate type piezoelectric vibrator is compact and easy to miniaturize. In this paper, simulation and finite element analysis of a multi-DOF motor with a rectangular piezoelectric vibrator as the stator are presented. The finite element model of the piezoelectric vibrator is established to analyze its vibration type under the B₃₂ and B₂₃ working modes. The main structural dimensions of the piezoelectric vibrator, including the aspect ratio and the thickness of the rectangular substrate, the width and height of the protrusion, are analyzed by computer simulation, which demonstrates the relationships between these structural parameters and the amplitude and the modal frequency of the piezoelectric vibrator. The principles to determine these structural dimensions are presented thereby.
