Piezo Electric ceramic Element/Piezo Speaker for Ultrasonic Motor

Piezo Electric ceramic Element/Piezo Speaker for Ultrasonic Motor 

Piezoceramic components, such as plates, disks or rings, convert mechanical signals, such as force, pressure, strain or acceleration, into electrical voltage, or, vice versa, an electrical voltage into mechanical motion or oscillations. The typical resonant frequencies are between 200 kHz and 10 MHz. The piezo elements are frequently used for generating ultrasonic oscillations, for example, in sensors or for high-power ultrasonic applications.

The shapes and dimensions of the piezo components can be selected within the limits determined by the tools, although the dimensions depend on each other. The minimum dimensions are determined by physical and technological limits. The thickness or wall thickness, for example, is limited by the mechanical strength of the ceramic during machining. In the polarization direction, the dimension is at most 30 mm.  

piezo ceramics into the customer’s product. This includes both the electrical contacting of the elements according to customer requirements and the mounting of components provided by the customer, and the gluing or the casting of the piezo ceramics. Piezo elements and components can also be delivered in large quantities at very short
