Piezoelectric impact motor (PIM) with high power driving capability has attracted extensive attention. This paper presents a new resonant-type PIM based on inertial drive mechanism. Architecture construction, dynamic modeling, and prototype experiment of the proposed motor are conducted. With sinusoidal driving voltages of 24 Vp-p at 435 Hz and 18 Vp-p at 870 Hz in the resonant mode, the prototype motor achieves an average no-load velocity of 26.1 mm s−1, a stalling drag force of 350 mN, and a power output capacity of 2.55 mW, while it also provides a stable step displacement of 0.67 μm with saw-tooth wave driving voltage of 20 Vp-p, 10 Hz in the stepping mode. Experiment results are consistent with the theoretical analysis, which confirms an effective approach to guide the structure design and further optimization for resonant-type PIMs.

基于惯性驱动机构的谐振式压电冲击电机的构建、建模与试验

具有大功率驱动能力的压电冲击电机(PIM)引起了广泛的关注。本文提出了一种基于惯性驱动机制的新型谐振式无源互调。对所提出的电机进行了架构构建、动态建模和原型实验。在谐振模式下,在 435 Hz时 24 V p-p和870 Hz 时18 V p-p 的正弦驱动电压下,原型电机实现了 26.1 mm s -1的平均空载速度、350 mN 的失速阻力和功率输出容量为 2.55 mW,同时它还提供 0.67 μ m的稳定步进位移,锯齿波驱动电压为 20 V p-p, 10 Hz 在步进模式下。实验结果与理论分析一致,证实了一种有效的方法来指导谐振型 PIM 的结构设计和进一步优化。
