A piezoelectric linear motor offering enhanced displacement is provided to reduce a manufacturing process and cost by forming a dome type piezoelectric ceramic without an extra elastic plate. A piezoelectric linear motor offering enhanced displacement includes a piezoelectric ceramic(100), an oscillating shaft(200), and a moving body(300). The piezoelectric ceramic(100) is a dome shape having different electrodes on both sides thereof and oscillates by protruding or denting in a shaft direction by the change of polarity of a voltage applied to the both sides thereof. The oscillating shaft(200) is fixed on a side of the piezoelectric ceramic(100) to be interlocked by the displacement of the piezoelectric ceramic(100). The moving body(300) is linearly driven by the friction with the oscillating shaft(200) simultaneously while contacting the oscillating shaft(200). |
