凹入部分

The piezoelectric motor includes a piezoelectric member which generates a first vibration mode and a second vibration mode simultaneously by an applied power and a frictional member of which a portion is insertedly attached into a concave portion indentedly formed on one side of the piezoelectric member, wherein the frictional member is in an elliptic motion by the vibration generated by the piezoelectric member, so that an influence of the attachment of the frictional member to a resonance frequency can be minimized.

该压电电机包括：压电构件，通过施加的功率同时产生第一振动模式和第二振动模式；摩擦构件，摩擦构件的一部分插入地附着到凹入地形成在压电构件的一侧上的凹入部分中，其中，摩擦构件通过由压电构件产生的振动进行椭圆运动，从而能够使附着摩擦构件对谐振频率的影响最小化。
