In the piezoelectric effect, the process of converting mechanical energy into electrical energy is called positive piezoelectric effect, and the process of converting electrical energy into mechanical energy is called inverse piezoelectric effect. The basic principle of the piezoelectric driving technology is a technical process that controls the mechanical deformation so as to generate rotation or linear motion based on the inverse piezoelectric effect of piezoelectric materials.
There are mainly three commonly used piezoelectric driving methods: direct-acting driving, stepping driving and inertia driving.
Direct-acting driving features compact structure, good continuity and strong power, but the range of stroke is small. It is often used in precision working platforms such as microscope and high precision machining.
The working principle of the stepping drive is based on the crawling characteristics of the reptiles in the nature, so it is also called a stepping linear drive, which is also called an inchworm type. This method is suitable for projects with large intensity, high resolution, and long strokes, and thus has a wide range of application prospects in the nano-micro operation technology.
The inertia driving is to generate a strong driving force by the piezo driver to drive the piezoelectric element for a larger displacement. It is generally a piezoelectric stack or a single/double piezoelectric brake with simple structures and the working frequency of over 1 kHz. It is suitable for high-resolution and large-stroke projects.
Piezo driver use inverse piezoelectric effect, which is an electromechanical coupling process in the energy conversion mode. It plays an important role in modern adaptive control systems and intelligent control systems. Its performance directly affects the reliability, controllability, and maintainability of the system. Due to the slow response, complicated structure, large volume, and difficult for maintenance, traditional drivers cannot meet the technical requirements of modern control systems.
ATI's piezo drivers are widely used in various precision mechanical and electromechanical integration projects for their high response speed, excellent performance, small size, light weight, easy control, no need for heat dissipation, low electromagnetic interference, and high energy conversion efficiency.
Piezo drivers have a wide range of application and research values in many fields such as aviation, aerospace, missile equipment, optics, biology, artificial intelligence, machinery, manufacturing, and precision instruments. Applications, such as ultrasonic motors, piezoelectric shock absorption, and noise reduction technologies, are also hot topics at present.
ATI has world-leading technology for piezo driver, which is best choice for you.
