    • In an energy recovery type surface acoustic wave motor, an increase in energy efficiency at the time of energy recovery and supply is achieved by adjusting phase change. A surface acoustic wave motor comprises: a surface acoustic wave substrate; a slider provided with an applied pressure; a driving interdigital electrode connected to an external power supply for generating a driving surface acoustic wave on a surface so as to drive the slider by a frictional force which is generated on a contact surface of the slider with the surface acoustic wave substrate based on the surface acoustic wave and the applied pressure; recovery interdigital electrodes placed forward and backward in the direction of travel of the surface acoustic wave for recovering energy of a surface acoustic wave unused to drive the slider, and for using that energy to generate a surface acoustic wave; and phase adjusting means for matching the phase of a surface acoustic wave generated by the recovery interdigital electrodes to the phase of the driving surface acoustic wave W generated by the driving interdigital electrode.
    • 在能量回收型表面声波电动机中,通过调整相变来实现能量回收供给时的能量效率的提高。 表面声波电动机包括:声表面波基板; 具有施加压力的滑块; 连接到外部电源的驱动交叉指状电极,用于在表面上产生驱动表面声波,以便通过在滑块的接触表面上产生的摩擦力来驱动滑动件,该摩擦力与表面声波基板基于表面 声波和施加的压力; 在表面声波的行进方向上向前和向后放置回收叉指电极,以恢复未被用于驱动滑块的表面声波的能量,并且使用该能量来产生表面声波; 以及相位调整装置,用于将由恢复叉指电极产生的表面声波的相位与由驱动叉指电极产生的驱动表面声波W的相位相匹配。
