我们提出了一个线性压电电机一样简单，一个压电扫描管（PST）的弹簧夹紧中心轴的两端大致相等的夹紧力。夹紧点与一端的+/- X电极和另一端的+/- Y电极对齐。因此，PST的+/- X（或+/- Y）推拉运动可以引起轴上的夹持点的推拉运动（称为推拉摩擦），这减小了PST的一端（或另一端）处的总动态摩擦力。这种新的压电电机前进一步，在一端快速推拉摩擦，同时慢慢收回PST，然后在另一端快速推拉摩擦，同时慢慢拉长PST。除了简单、严格、完整等明显的优点外，我们还将表明，这种电机可以产生很大的输出力，我们认为这是因为当推拉摩擦发生时，夹紧摩擦力的巨大下降。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4767246]
We present a linear piezoelectric motor as simple as one piezoelectric scanner tube (PST) spring-clamping a central shaft at both ends with roughly equal clamping forces. The clamping points are aligned with +/- X electrodes at one end and +/- Y electrodes at the other end. Thus, the +/- X (or +/- Y) push-pull motions of the PST can cause the push-pull motions of the clamping points on the shaft (called push-pull rubbing), which reduces the total dynamic friction force at one (or the other) end of the PST. This new piezo motor advances one step by fast push-pull rubbing at one end while slowly retracting the PST followed by fast push-pull rubbing at the other end while slowly elongating the PST. Apart from the obvious advantages of simplicity, rigidity, integrity, etc., we will also show that this motor can produce a large output force, which we believe is because of the huge drop of the clamping friction force when the push-pull rubbing occurs.
