2025-06-01
Piezoelectric ceramic series products have the following core advantages:
High-precision displacement control: Through multi-layer stacking technology, the displacement resolution can reach nanoscale, which 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, it can quickly respond to electrical signals, realize fast action and precise control, and meet the needs of high-speed precision control.
Zero hysteresis characteristics: the repeated positioning error is less than 0.1% under closed-loop control, with good repeatability and stability, can provide accurate and reliable displacement output, and is suitable for applications requiring high-precision repeated positioning.
Strong environmental adaptability: It can maintain stable performance in harsh environments such as vacuum, strong magnetic field, and extreme temperature, making it an irreplaceable role in special environmental fields such as aerospace and deep-sea exploration.
