Piezoelectric ceramic series products have the following core advantages: high-precision displacement control: through multi-layer stacking technology, the displacement resolution can reach nanoscale, and can achieve high-precision displacement output, such as in the semiconductor lithography machine can meet the requirements of the workpiece stage nanoscale positioning accuracy. High energy density: The output force per unit volume is large, up to 500N or more, which is 10 times that of an electromagnetic motor. It can generate a larger driving force in a smaller volume and is suitable for precision driving scenarios with limited space. Fast response: with millisecond response speed, can quickly respond to electrical signals, to achieve fast action and precise control, to meet the high-speed precision
