Description

technical field [0001] The invention relates to the technical field of precision engineering, in particular to an auxiliary booster piezoelectric stick-slip linear motor and an excitation method thereof. Background technique [0002] Piezoelectric stick-slip linear motor is a kind of inverse piezoelectric effect based on piezoelectric elements, which excites the stator (or vibrator) under the excitation of asymmetrical electric signals to produce small-amplitude high-frequency vibration, which is realized by the friction coupling between the stator and the mover. A micro-nano precision piezoelectric stick-slip linear motor with mechanical energy output. According to different driving principles, piezoelectric stick-slip linear motors are mainly divided into two categories: resonant piezoelectric motors (also called ultrasonic motors) and non-resonant piezoelectric motors (also called piezoelectric stick-slip motors). Compared with the resonant piezoelectric motor, the piezo...
