Piezoelectric Ultrasonic transducer
The Ultrasonic transducer, itself a piezoelectric ceramic chip that resonates at the same frequency, uses the piezoelectric effect of the raw material to convert electrical energy into mechanical vibrations. Under normal circumstances, ultrasonic waves are generated by ultrasonic generators, which are converted into mechanical vibration by Ultrasonic transducer, and then can be generated by ultrasonic-guided equipment and ultrasonic-receiving devices.
Application of Ultrasonic transducer:
Ultrasonic cleaning machines take advantage of the gradual spread of ultrasonic waves through the cleaning fluid to clean stains on objects. The frequency of ultrasonic vibration is determined by the Ultrasonic transducer, depending on the cleaning material to set a different frequency to achieve the goal of cleaning.
The Ultrasonic welding takes full advantage of the Ultrasonic transducer to cause ultrasonic vibrations that cause friction and cause the weld areas to melt locally, thus joining them together.
Instead of adding Ultrasonic transducer to the Ultrasonic motor, it uses the piezoelectricity to create ultrasonic vibrations, which cause the rotor to rotate as it rubs against the stator.
