Abstract:

A novel rotational inertial piezoelectric motor was proposed. The equation of inertial impact torque and the average output torque of rotary inertial piezoelectric motor were derived in asymmetric excitation signals. The influences of system parameters on the difference of inertia impact torque of excitation signal mutation moment were analyzed. The optimal driving frequency range of output speed and torque of the rotary inertial piezoelectric motor were given. With experimental system, the correctness of theoretical calculation and analysis was verified.

Key words: inertial impact torque, output torque, drive frequency, mutant moment
