Abstract

Generally, ultrasonic motor driving principles use vibration along an elliptical locus. In this research, a principle using an 8-shaped vibration locus is proposed. The proposed system has merits such as a single driving power source and precise positioning. Control technique and a design method of optimum stator transducer to realize the driving principle are reported.
