摘要： A piezoelectric ultrasonic motor includes a piezoelectric stator including a metal tube with an inner space and piezoelectric elements mounted on the outer circumference of the metal tube, a rotary shaft including a rotation bar inserted into the inner space of the metal tube, and a rotation member provided around the rotation bar in contact with the piezoelectric stator. The piezoelectric stator strains with an electric field applied thereto, and the rotation member rotates in response to the strain of the piezoelectric stator. A power transmission member is provided at one portion of the rotation bar to transmit the rotation of the rotation member to an object to be transported. With face contact the motor achieves stable actuation together with enhanced force and sufficient strain, and a flexibility to be applied to various apparatuses such as a camera module.
