Hollow Voice Coil Motors (VCMs) have a variety of applications in vision systems that utilize their high accuracy, high responsiveness, and wear-free characteristics. The main application of Voice Coil Motor in vision system is autofocus, which is widely used in the autofocus system of cameras and microscopes. By precisely controlling the movement of the lens set, the VCM is able to realize fast and accurate focusing to ensure clear images. In industrial production lines, vision inspection systems need to accurately position and scan product surfaces. Hollow voice coil motors are able to improve inspection accuracy and efficiency through their high precision and fast response capability. In cameras and smartphone cameras, hollow voice coil motors are used to compensate for hand tremors or other small movements.VCMs can quickly adjust the position of the lens or sensor to keep the image stable and reduce blurring.

Technical Parameters:

The hollow motor is a coreless rotary motor and a voice coil motor with internal through-holes, designed to provide high torque and coreless power motors. With a maximum stroke of 20 mm, a maximum voltage of 78V and a coil length of 53 mm, it is efficient and reliable. It has high response, high acceleration, low mass coil, no slot effect, and zero hysteresis. Simple structure, light weight, high frequency response, smooth operation characteristics, is also an ideal choice for precision positioning, a wide range of applications, widely used in optical scanning, positioning and autofocus systems, Its hollow design reduces power consumption and provides quieter operation.

voice coil motor:

1.Travel: effective travel, used to calculate the the total travel of value force.

2.The direction of movement: horizontal or vertical installation 90 degree.

3.Load force: constant in the reverse direction of force on the motor, such as springs, etc.

4.Load weight: the total quality part of movement, including the quality slider

5.Movement Type: 1.point to point movement; 2.the reciprocation of the rule (e.g. scanning).

6.Velocity curve: 1.a trapezoidal speed curve; 2.triangular speed curve; 3.sine speed curve.
