Ultrasonic motors using longitudinal and torsional motions of rod vibrators have previously been proposed. Several motor constructions, whose forms are different from the previous ones, are proposed and their characteristics are experimentally examined in order to develop the ultrasonic motors of this type; that is, they are expected to have much different uses, according to how their forms are modified. Two groups of motor are dealt with: one contains motors basically suited to the relatively high torque of 2-3 kgf-cm and the other contains motors for small or medium torque below about 1.0 kgf-cm. As the result, operational characteristics of motors are totally revealed. These are useful in developing the rod type ultrasonic motors and in their practical applications.
此前已有人提出利用棒状振子的纵向和扭转运动的超声波电机。为了开发这种类型的超声波电机，提出了几种结构形式与以往不同的电机，并对其特性进行了实验研究；也就是说，根据其结构形式的改变，预计它们会有非常不同的用途。研究了两组电机：一组是基本适用于2-3千克力厘米相对高扭矩的电机，另一组是适用于低于约1.0千克力厘米的中小扭矩的电机。结果，完全揭示了电机的运行特性。这些对于开发棒式超声波电机及其实际应用很有用。
