Abstract

The invention discloses a singe-stimulating linear ultrasonic motor. A rotor comprises a sliding strip and a friction layer arranged on the surface of the sliding strip; a stator comprises an ultrasonic vibration transducer, an elliptical vibration modal converter and a friction driving block arranged at the front end of the elliptical vibration modal converter; the ultrasonic vibration transducer comprises bolts and a rear cover plate, a piezoelectric ceramic piece, an electrode sheet and a front cover plate which sleeve the bolts in sequence; the rear cover plate and the front cover plate are used for connecting and pressing the rear cover plate, the piezoelectric ceramic piece, the electrode sheet and the front cover plate through the bolts; the elliptical vibration modal converter is arranged at the front end of the ultrasonic vibration transducer and is of a composite structure with a straight beam and an inclined beam; the elliptical vibration modal converter can be used for converting longitudinal ultrasonic vibration generated by the ultrasonic vibration transducer into longitudinal bent composite ultrasonic elliptical vibration at the tail end of the elliptical vibration modal converter and the friction driving block and driving the rotor to do continuous linear motion.

Description

technical field [0001] The invention relates to the field of ultrasonic motors utilizing the inverse piezoelectric effect of piezoelectric ceramics, in particular to a linear ultrasonic motor utilizing single excitation ultrasonic elliptical vibrations. Background technique [0002] The linear ultrasonic motor is a new type of micro-motor developed and applied rapidly in the 1980s. It is an electromechanical coupling device that uses the inverse piezoelectric effect of piezoelectric materials to convert electrical energy to mechanical energy. Through the friction between the stator and the mover, Convert the micro-vibration of the elastic body into the macroscopic linear (rotational) motion of the mover to directly push the load. Because of its small size, light weight, low speed and high torque, low noise, fast response, high positioning accuracy, no electromagnetic interference and strong environmental adaptability, it has been increasingly widely used in medical, aerospac...
