A 3DU12L, short for three-dimensionally deformed ultrasonic single-axis stage, is a motor-driven actuator used for displacement control in closed-loop applications. The 3DU12L is a piezoelectric transducer-based device that converts electrical signals into ultrasonic vibrations which are used to produce two-way linear motion with nanometer resolution. The 3DU12L incorporates a base plate, a piezoelectric transducer, and a displacement actuator. The displacement actuator is a linear stage with feedback control, composed of two high-precision lead screws and a motor. The electrical signals control the motor’s speed and the piezoelectric transducer’s frequency, which in turn produce the linear motion. The acceleration and deceleration of the motor are controlled by the 3DU12L’s feedback control system.

3DU12L is widely used in optical imaging, electronic microscopy, automated optical inspection, interferometry, and many other applications. It can achieve nanometer resolution and repeatability while providing high bandwidth and fast responsiveness.

The 3DU12L can operate using a range of driving frequencies and an ultrasonic vibrational force, which enables a wide variety of stage movements. It can be used for any one-dimensional movement, such as zooming, focusing, imaging, scanning, and sweeping. It is also ideal for various motion control applications including high-precision position control, monitoring, and feedback systems.

The working principle of the 3DU12L can be understood by looking at its configuration. The device has an actuator, which is a linear stage composed of two precision lead screws and a motor, and a piezoelectric transducer. When an electrical signal is applied to the piezoelectric transducer, it converts the signal into ultrasonic vibrations. The vibrations cause the two lead screws to move in opposite directions, producing linear motion. The motion is then translated into displacement signals which are then used to control the motor’s speed. This allows the 3DU12L to achieve nanometer resolution and repeatability.

The 3DU12L has a number of advantages over traditional piezoelectric transducer-based devices, such as higher resolution and increased repeatability. It is also more efficient and reliable and can be used in a variety of applications. Its rugged, compact design makes it ideal for a range of aerospace, automotive, and industrial applications.

In conclusion, the 3DU12L is a motor-driven actuator used for displacement control in closed-loop applications. It converts electrical signals into ultrasonic vibrations which are used to produce two-way linear motion with nanometer resolution. It is widely used in optical imaging, electronic microscopy, automated optical inspection, interferometry, and many other applications. It can operate using a range of driving frequencies and an ultrasonic vibrational force, which enables a wide variety of stage movements. It has a number of advantages over traditional piezoelectric transducer-based devices, and is ideal for various motion control applications including high-precision position control, monitoring, and feedback systems.
