초록
In this paper, a novel design ultrasonic linear motor is proposed. The proposed motor consists of a ring type stator and a mover. They have spirals on their inner and outer surface, respectively. Along the spiral, a mover is travelled by a travelling extensional vibration mode of a ring type stator. Hence, a linear up-and-down motion is generated. Through the experimental data, we can verify the applicability regarding the autofocus lens drive.
