我们提出了一种新的堆叠TunaDrive电机与两个完整的压电堆被弹簧夹持的一对平行的高度抛光氧化锆陶瓷棒。与我们提出的早期版本相比，它具有更简单，更紧凑的结构，更容易构建。虽然压电材料的使用量减少了1.35%，但电机仍然可以提供1.92N的大输出力，这与早期版本几乎相同。该电机结构简单、对称、刚度高、输出力大，是纳米级精度粗加工的理想工具。
We present a new stacked TunaDrive motor with two intact piezoelectric stacks being spring-clamped by a pair of parallel highly polished zirconia ceramic rods. Compared with the earlier version we presented with five stacks, it has a simpler and more compact structure and is much easier to build. Although the usage of piezoelectric material is cut by ∼35%, the motor can still provide a large output force of ∼1.92 N, which is nearly the same as that of the earlier version. The simple and symmetrical structure, high rigidity, and large output force make the new motor an ideal tool for coarse approach with nanometer precision.
