利用硅微机械加工技术和金属微机械元件制作了一种混合型超声波电机。弹性力马达(EFM)的概念被应用于驻波到机械能的转换。毫米尺寸的原型(6*6*2 mm)显示出有趣的特性。观察到自由旋转速度高达600 rpm,净扭矩为50 nNm。典型应用是电子表的电动化或仪器仪表中的定位系统。&lt;<ETX>&gt;
A hybrid ultrasonic motor has been fabricated using silicon micromachining and metallic micromechanical components. The concept of elastic force motors (EFMs) is applied for the conversion of standing waves to mechanical energy. Millimeter-size prototypes (6*6*2 mm) show interesting characteristics. Free rotation speed up to 600 rpm and net torque of 50 nNm are observed. Typical applications are the motorization of electronic watches or the positioning systems in instrumentation.<<ETX>>
