- 論文の詳細を見る
This paper deals with an ultrasonic linear motor using nonaxisymmetric ((1, 1)) vibration and radial (R, 1) vibration modes of a piezoelectric ceramic annular plate. A new method of making these modes degenerate is proposed. By applying this method to a vibrator, the neutral axis of vibration for ((1,1))-mode is fixed on the prescribed position, and the difference between the two resonance frequencies is adjusted to the optimum state for a stator vibrator. The construction and some operational characteristics of the linear motor are presented. The maximum efficiency of the prototype motor was about 48%.
