摘要： A piezoelectric ultrasonic motor includes a piezoelectric stator including a metal tube with an inner space and piezoelectric elements mounted on the outer circumference of the metal tube, a rotary shaft including a rotation bar inserted into the inner space of the metal tube, and a rotation member provided around the rotation bar in contact with the piezoelectric stator. The piezoelectric stator strains with an electric field applied thereto, and the rotation member rotates in response to the strain of the piezoelectric stator. A power transmission member is provided at one portion of the rotation bar to transmit the rotation of the rotation member to an object to be transported. With face contact the motor achieves stable actuation together with enhanced force and sufficient strain, and a flexibility to be applied to various apparatuses such as a camera module.

摘要： A vibration driven motor of a construction in which the hardness of the sliding surface of a vibration member is lower than the hardness of the sliding contact portion of a member brought into pressure contact therewith, and the lateral width of the sliding contact portion of the vibration member is smaller than the width of the sliding contact portion of the member brought into pressure contact therewith, whereby the sliding member of the vibration member is caused to wear more than the sliding member of the member brought into pressure contact therewith, thereby to facilitate the discharge of the wear powder thereof and to eliminate the level difference wear of the movable member attributable to the comb-shaped projections and the deterioration of the planarity of the movable member similar thereto. Also, this structure prevents deterioration of accuracy in motor performance when a stopping or starting operation occurs at the same location, or when operating at extremely low speed control is effected, and abnormal wear of the sliding surface of the vibration member is prevented.
摘要翻译：一种振动驱动电动机，其特征在于，振动部件的滑动面的硬度低于与其成为压力接触的部件的滑动接触部的硬度，振动的滑动接触部的横向宽度构件比与其压接的构件的滑动接触部分的宽度小，由此使振动构件的滑动构件比与构件压力接触的构件的滑动构件更磨损，从而便于排出其磨损粉末，并且消除归因于梳形突起的可动构件的水平差磨损以及类似于其的可移动构件的平面度的劣化。此外，该结构防止在同一位置发生停止或起动操作时，或者以极低速度控制进行操作时电机性能的精度降低，并且防止振动构件的滑动面的异常磨损。
