Description

technical field [0001] The patent of the present invention relates to a low-frequency piezoelectric motor, in particular to an inertial impact low-frequency piezoelectric motor. Background technique [0002] At present, the phenomenon that vibration can form driving ability through appropriate structural transformation has been known and successfully applied for many years. The operating frequency of ultrasonic motor is above 20kHz, and the rotor is usually driven by the formed absolute elliptical coupling motion. Therefore, in theory, as long as the vibration is synthesized into elliptical coupling motion (or relative elliptical coupling motion) through a suitable structure, low-frequency vibration can also form a driving force, and it can be used to construct a motor like ultrasonic vibration. However, the existing low-frequency Due to the unreasonable structural design of the motor, there are generally problems of low vibration efficiency and poor pitching effect during u...
