30kHz 800W High Quality Ultrasonic Plastic Welding Transducer Piezoelectric Ceramic Transducer
When a voltage is applied to the two poles of a piezoelectric chip, due to the inverse piezoelectric effect of the piezoelectric ceramic material, the piezoelectric chip undergoes deformation in the thickness direction (i.e. the axial direction of the transducer), which is repeatedly stretched and compressed under the action of alternating current to convert electrical energy into mechanical energy. Under the action of alternating current, the oscillator undergoes periodic stretching and compression deformation at the resonant frequency, which also drives the amplitude modulator to resonate. In this way, the oscillator and the amplitude modulator each become a simple harmonic vibration unit. The oscillator is excited by the electrical signal, and then the amplitude modulator is excited, causing both to resonate. While each resonant unit outputs axial amplitude, it also undergoes periodic deformation in the radial direction. At both ends of the unit, the axial deformation is maximum, while the radial deformation is minimum, while the position of the intermediate node is opposite. The structural gain of the resonance unit is proportional to the mass ratio at both ends of the node. The amplitude generated by the ultrasonic transducer depends on the structural gain of the vibrator and the amplitude modulator, and also on the applied voltage. The output amplitude affects the output power of the ultrasonic transducer. The greater the amplitude, the higher the voltage, and the higher the output power.
