Bidirectional motion characteristics of a single harmonic-driven self-clamping linear piezoelectric motor [PDF]
Review of Scientific Instruments, 2022 We propose a multimodal model to realize the bidirectional motion of a self-clamping linear piezoelectric motor driven by a single harmonic signal based on previous motor research. Compared with the previous version, only the characteristics of the drive signal need to be changed in the motor without changing any other conditions to excite multimode ...
