Superior lifetime of our actuators is guaranteed with the patented ceramic-encapsulated multilayer production process. A piezoelectric actuator converts an electrical signal into a precisely controlled physical displacement (stroke). Maximum forward and reverse flow rates of 2 mL/min and 1.2 mL/min are reported respectively and the maximum backpressure is 170 mbar at 200 V. This group is specialized in research, design and manufacture of piezo materials and components for motion control. In this article, a novel two-stage flow control valve driven by amplified piezoelectric actuator is proposed, fabricated, and tested with the step response time of 5 ms, flow rate of 70 L/min, and. The capacitance is a task of the excitation voltage frequency and resonance is the frequency where the piezoelectric actuators react with the highest o/p. Piezo actuator applications for operation at or near. We currently employ 180 staff at our piezo ceramics division " PI Ceramic". Multiple piezos can be used to provide a stronger haptic response and more localized haptic feedback. PI offers the largest selection of standard and custom piezo actuators and engineered subassemblies. They provide efficient force generation because no conversion from rotary to linear motion and no gears or mechanical other parts that require maintenance or lubrication are involved. Some of these models have been improved to consider rate-dependent hysteresis, such as the improved Preisach model 12,13 and the improved PrandtlIshlinskii.
