A novel piezoelectric motor with synchronous anchoring/loosening control of harmonic vibration was proposed. It was composed of a resonant vibrator and a synchronous clamp clutch. Its output components were made to generate a linear motion along linear guide by combining the resonant actuation of ultrasonic motors and the control mechanism of inchworm motors. The motor's operation and driving mechanism was analyzed in detail. A prototype motor was fabricated, tested and analyzed. The test results showed that the piezoelectric motor with synchronous anchoring/loosening control has excellent characteristics.
