N2 - This article proposes a flexible ultrasonic motor that consists of a single metal cube stator with a hole and an elastic elongated coil spring inserted into the hole. When voltages are applied to piezoelectric plates on the stator, the coil spring moves back and forward as a linear slider. The use of the coil spring brings flexibility for the motor and enables a long stroke to access to deeper sites. Furthermore, the coil spring provides an appropriate prepressure between the stator and the coil spring to enhance the motor output. We formulate the relation between the coil spring parameters and the prepressure to clarify the design methodology of the flexible ultrasonic motor. We model the linear motion of the coil spring by an equation of motion and compare it with the transient response by experiments. The flexible ultrasonic motor prototype achieved a translation at a speed of 120 mm/s and demonstrated a force of 0.45 N, and a stable motion even when the coil spring is being bent.
