Different sizes of piezoelectric ceramics used for ultrasonic motors(一)

high mechanical quality of the piezoelectric transducerAbout high mechanical quality factor Q, it can improve the efficiency of the piezoelectric transducer (vibrator) and reduce the loss (7) Wide operating frequency band. In fact, it is difficult at present to have a

The performance of piezoelectric ceramic materialsBecause of its low energy consumption, fast response, high rigidity easy control and piezoelectric ceramic materials can be affixed to the surface of the body structure or can be embedded inside the body structure, and the production

PZT-based piezoelectric ceramics ultrasonic sensorThe same sodium barium titanate also has the characteristics of low piezoelectric activity, large coercive field, and the like. At present, sodium barium titanate is mainly modified by adding a variety of perovskite structure dopants. When TiO3 for u
