【摘要】 多自由度超声电机是将两种以上的超声振动模式按照一定的方式组合,通过在定子的表面产生椭圆运动来实现转子的多自由度转动.文中综述了近年来发展起来的几种多自由度超声电机的结构、工作原理和特征,并就多自由度超声电机的工程应用和未来发展方向进行了展望.更多还原

【Abstract】 By synthesizing two or more vibration modes the multi-degree-of-freedom ultrasonic motor can produce elliptical motion on the surface of the stator and make the rotor rotate around the three axes. We describe the structure, operation and applications of these motors. Recent and future developments are discussed.更多还原
