role of piezoelectric ceramic chip ultrasonic motor

With the rapid development of technology, piezoelectric ceramic chip ultrasonic motors also get a comprehensive type of development, but it is part of one of the piezoelectric ceramic chip secret weapon, why do you say so? 

Ultrasonic motors have been able to complete so many "tough action", mainly but also thanks to its structure and characteristics. 

       It is mainly the use of the properties of piezoelectric ceramic wafer made of. And this is what we said here's "secret weapon." 

Piezoelectric ceramic chip, also called a buzzer people, is an electronic pronunciation components. It is the use of piezoelectric ceramic works, in the middle of two pieces of copper circular electrode placed piezoelectric ceramic dielectric material, when the above two electrodes connected to AC audio signal, the piezoelectric film will be based on the size of the frequency of the signal to produce the corresponding sound vibration occurs. 

In the use of the process should pay attention: To make a good closed to prevent dew, rain and dust intrusion. The piezoelectric ceramic is fixed inside the top of the metal box body. While the base is fixed to the open end of the cartridge body, and the use of resin coverage. 

     Used in industrial robots for ultrasonic sensors, require an accuracy to reach 1mm, and has a strong ultrasonic radiation. 

     Piezoelectric ceramic chip simply because of its low cost structure, is widely used in electrical and electronic aspects such as: toys, pronunciation electronic watches, electronic equipment, electronic watches and clocks, timers, as well as other aspects of the ultrasonic motor.
