A rotary inchworm piezoelectric motor was presented.The driving principle of the motor and the configuration design of the clamping mechamisms were introduced.Considering the bending and torsion deformations of a lever amplifcation beam and a long flexible beam,the dynamic model of clamping mechamisms was established.The first eight natural frequencies and modal functions were given.The effects of structure parameters of clamp mechanisms on the natural frequencies were discussed.The test results illustrate the correctness of the theoretical analysis.
