What is the piezoelectric transducer of ultrasonic cleaning machine?

The principle of piezoelectric ultrasonic transducer is:

Ultrasonic transducers, which are piezoelectric ceramics at the same frequency as their resonance, use the material's piezoelectric effect to convert electrical energy into mechanical vibration. In general, the ultrasonic wave is first produced by the ultrasonic generator, which is converted into mechanical vibration by the ultrasonic transducer, and then produced by the ultrasonic export device and the ultrasonic receiving device.

Application of ultrasonic transducer:

(1) Ultrasonic cleaning machine uses ultrasonic in the cleaning liquid to continuously spread to clean the dirt on the object, the ultrasonic vibration frequency is determined by the ultrasonic transducer, can be set according to the cleaning of different frequencies to achieve the purpose of cleaning.

(2) Ultrasonic welding machine uses ultrasonic transducer to produce ultrasonic vibration, vibration produces friction to make the welding area local fusion and then join together.

(3) There is no ultrasonic transducer in the ultrasonic motor, but the stator is approximated as a transducer. Ultrasonic vibration is generated by the inverse piezoelectric effect, and the rotor is driven to rotate by the friction between the stator and the rotor.
