Description

technical field [0001] The invention relates to a rotating motor using a composite bending-vibration biped linear ultrasonic vibrator, belonging to the technical field of piezoelectric ultrasonic motors. Background technique [0002] Piezoelectric ultrasonic motor uses the inverse piezoelectric effect of piezoelectric ceramics to excite vibration in the ultrasonic frequency band in the elastic body, and forms a particle motion with a specific trajectory at a specific point or area on the surface of the elastic body, and then passes between the stator and the rotor. The friction coupling converts the microscopic motion of the particle into the macroscopic motion of the rotor. The piezoelectric ultrasonic motor has the advantages of low speed and high torque, no need for a speed change mechanism, no electromagnetic interference, fast response, and self-locking when power is off. [0003] Due to the simplicity of the excitation principle and the simplicity of the theoretical an...
