Abstract
The present invention provides an ultrasonic motor having a two-sided teeth metal-plastic compound stator, and relates to an ultrasonic motor. The objective of the invention is to solve the problems that an ultrasonic motor with single-sided teeth plastic stator is small in output power and low in driving efficiency. The ultrasonic motor comprises housing and a pedestal which are connected together; the ultrasonic motor also comprises a two-sided teeth stator module, an upper rotor and a lower rotor; the two-sided teeth stator module comprises two metal-plastic compound stators; each metal-plastic compound stator comprises a stator metal matrix and a tooth-shaped plastic stator which are connected into one body, and the middle portion of each metal-plastic compound stator is provided with an installation hole; the two stator metal matrixes are abutted joint and a piezoelectric ceramic piece is glued between the two stator metal matrixes; and a cavity is internally provided with the upper rotor and the lower rotor which are connected together for linkage, the cavity is internally provided with the two-sided teeth stator module installed on the pedestal, and the wheel flange end surfaces of the upper rotor and the lower rotor are in contact with the teeth surfaces of the corresponding tooth-shaped plastic stators. The ultrasonic motor having a two-sided teeth metal-plastic compound stator is taken as a driver.
Description
technical field [0001] The invention relates to an ultrasonic motor, which belongs to the field of piezoelectric driving. Background technique [0002] Ultrasonic motor is a new type of driver that uses the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy. The excitation of the same frequency mechanical vibration in the body, and then the particles in the stator drive area form a driving trajectory, and the output of the macroscopic motion of the rotor is realized through the friction coupling between the stator and the rotor. [0003] The publication number is CN201742324U, the publication date is February 09, 2011, and the invention name is "rotary traveling wave ultrasonic motor", which does not use a double-sided tooth stator, nor does it use a metal-plastic composite stator. This utility model application still has high cost and heavy weight, the publication number is CN101702592A, the publication date is May 5...
