 piezo ceramic tube |  piezoelectric tube sensor |  frequency of piezoelectric tube |
The correlation between the performance of the PZT piezoelectric ceramics and the performance of the ultrasonic motor, it is the admittance, load, startup, and temperature characteristics of the piezo ceramic tube were discussed. The results show that the motor has good transient characteristics, startup time is 2 ms, off-time is l Ins. Using P-41 piezoelectric ceramic motor starts shut-off speed. The fastness of PZN-PZT piezoelectric ceramic motors is related to the non-relaxation phase,which change characteristics of P-41 piezoelectric ceramics, which shows that
P-41 piezo knock sensor is more suitable for ultrasonic motors that require repeated switching. At the same time, the Qm of the P-41 motor is relatively small and has a good load capability. The surface temperature of the motor rises rapidly with the extension of the operating time, and eventually frequency of piezoelectric tube runs stably at a certain temperature. The surface temperature of the PZT piezoelectric ceramic motor is significantly lower than that of the P-41 piezoelectric ceramic.The PZT piezoelectric ceramic has a very low temperature. The dielectric loss of piezoelectric tube sensor is relevant, so this material is more suitable for ultrasonic motors that require long-term operation. Pre-pressure has a great influence on the performance of the motor.different sizes have different driving performance.
Piezoelectric materials are used for making ultrasonic transducers including piezoelectric material piezoceramic rings ,polycrystalline piezoelectric ceramics, piezoelectric polymers, and piezoelectric composites. Among them, lead zirconate titanate piezoelectric ceramics have high mechanical strength and temperature resistance and humidity resistance. The advantages of low cost and good electro mechanical coupling effect have been widely used in ultrasonic transducers.piezo transducer datasheet is used in ultrasonic range finder which are piezoelectric ceramics with lead zirconate titanate as vibrator.
