Rotary voice coil motor is a kind of drive device that utilizes electromagnetic induction principle to convert electrical energy directly into linear or angular displacement, which is widely used in various high-precision positioning control fields.
In scanning systems, which include laser scanners, optical imaging, barcode scanning, scanning microscopes, etc.; rotary voice coil motors are usually used to drive reflector lenses or prisms, so that the laser beam is scanned quickly and accurately in accordance with a set path.
For example, in LIDAR and barcode readers, the rotary voice coil motor drives the lens to oscillate at a small angle at high speed to realize scanning in the X-Y direction.
In medical imaging equipment such as optical coherence tomography, rotary voice coil motors can be used to rapidly move optical components for multi-layer, multi-angle imaging.
In scanning microscopes, rotary voice coil motors are used to control the position of the probe head or sample stage, realizing rapid image or signal acquisition and improving imaging speed and resolution.
In printing and scanning equipment the VCM is used to move the scanning head or adjust the lens focus for accurate, high-speed scanning of images or documents.
Rotary voice coil motorized sub-coils are lightweight,short response time,high frequency,high precision positioning.
Swing angle: 1-100 degrees
Torque: 1-50N.m
Widely used in optical scanning, positioning, focusing, etc., the precision control field of fast mirror.
Modular design, can be customized.
