The piezoelectric motor includes a piezoelectric member which generates a first vibration mode and a second vibration mode simultaneously by an applied power and a frictional member of which a portion is insertedly attached into a concave portion indentedly formed on one side of the piezoelectric member, wherein the frictional member is in an elliptic motion by the vibration generated by the piezoelectric member, so that an influence of the attachment of the frictional member to a resonance frequency can be minimized. Accordingly, a driving efficiency of the piezoelectric motor can be improved. In addition, attachment strength of the frictional member can be improved.

    摘要: In a driving and control apparatus of a piezoelectric ultrasonic motor, a controller controls a selection of a first channel or a second channel of the piezoelectric ultrasonic motor as a driving channel. A switch part selects one of the first and second channels as the driving channel and the other as a detection channel, and supplies the driving voltage to the piezoelectric ultrasonic motor through the selected driving channel. A phase detector detects a voltage outputted from the piezoelectric ultrasonic motor through the detection channel, calculates a phase deviation, and outputs a phase difference voltage corresponding to the phase deviation. A voltage controlled oscillator generates the oscillation voltage and controls a phase of the oscillation voltage according to the phase difference voltage. A frequency divider divides the oscillation voltage by two to generate the driving voltage, and supplies the divided oscillation voltage to the piezoelectric ultrasonic motor through the driving channel.
