Their application status piezoelectric folds, and piezoelectric actuator folding

摘要

As shown in Figure 3, (1) is folded in the same direction the piezoelectric element in the stator (11) on. Fixed end of piezoelectric elements (1) (6) are fixed base (4), a voltage is applied to (1) the piezoelectric element, the open end piezoelectric element (1) to (7) base (4) I extend in the opposite direction of the. When you generate a sawtooth wave (12) is shown in FIG. 4 (a) drive unit, the piezoelectric element (1) Because the contraction and slowly expanded rapidly, is sprung by (1) the piezoelectric element slider (21) I want to move while. If Figure 4 (b), the piezoelectric element (1) Since the expansion slowly shrinks rapidly, the slider (21) to move while being dragged by (1) the piezoelectric element on the other hand. By arranging in a circular piezoelectric element (1) as shown in Figure 13, (11) can rotate (35) the sphere circle rotor and rotor (31) status.
