电动机是最重要的致动器之一，并且其小型化在市场上被强烈期望，以便使机电系统尽可能小。超声波马达在商业上应用于照相机等的聚焦装置，并且存在进一步的需求来使它们小型化，以便适用于移动的电话、汽车致动器和诸如IVUS的显微外科手术装置。然而，传统的超声波电机都是基于表面传播和传递振动波，不可避免地需要很多零件，而且对小型化有一定的限制。考虑到这些问题，本论文提出了一种新的概念[1，2]，其中线圈型定子直接接触在圆柱形转子上，因此，结构变得非常简单，并且可以实现小型化。提出了四种不同类型的想法和原型，制造并测试了它们的基本性能。
The motor is one of the most important actuators and its miniaturization is strongly desired in the market in order to make electro – mechanical systems as small as possible. Ultrasonic motors are commercially applied to a focussing device of camera and etc. and there exists further demands to miniaturize them so as to adopt to mobile phone, automobile actuators, and micro surgery devices like IVUS. However, the conventional ultrasonic motors are based on a surface propagation and transmission of vibration wave, inevitably, they need many parts and there is a certain limit to miniaturize. Taking these points into account, the present paper proposes a new concept [1,2] in which a coil type stator contacts on a cylindrical rotor directly, hence, the structure becomes very simple and can realize miniaturization. Four different types of ideas and prototypes are proposed, manufactured and tested their fundamental performances.
