Product Description
Product Description:
The SUPT rotary voice coil motor is a specialized form of direct drive motor that converts electrical energy into torque, enabling rotational motion over a finite angle.
Rotary voice coil motors are widely adopted in optical and laser technology due to their high precision, rapid response, compact size, and excellent linearity between output torque and current.
Optical systems demand extreme precision and responsiveness for angular micro-adjustments. The linear control characteristics and low inertia of rotary voice coil motors meet these requirements. In lidar, laser communication, and laser processing equipment, they drive mirrors and prisms for minute angular rotations, enabling rapid laser beam scanning, focusing, or pointing calibration. This ensures beam positioning accuracy at the micrometer or even nanometer level.
In high-precision imaging equipment like industrial cameras and astronomical telescopes, RCMs fine-tune the optical axis angle of lenses and filter switching angles. They compensate for optical aberrations caused by vibration or temperature changes, guaranteeing imaging clarity.
Within analytical instruments, RCMs drive the rotational angle of gratings or monochromators to precisely select specific wavelengths of light, enabling high-accuracy detection of material composition.
SUPT's Rotary Voice Coil Motors represent an excellent choice.

Applications:
Specific Applications of SUPT MOTION's Rotary Voice Coil Motors in the Optical Field:
1. In laser scanning and beam positioning: For LiDAR systems and laser processing equipment, rotary voice coil motors drive two-dimensional galvanometers to achieve rapid, precise angular control, enabling fast laser beam scanning and accurate positioning. By controlling the galvanometer's rotation across two degrees of freedom (X-axis and Y-axis), the laser beam can be precisely directed to target locations, ensuring micron-level or even higher beam positioning accuracy.
2. In high-end cameras, astronomical telescopes, and other imaging equipment, RCMs are used for fine-tuning the optical axis angle of lenses and switching filter angles.
3. In optical scanning mirrors: RCM-driven mechanisms enable multi-angle mechanical tilt. Their built-in high-precision position feedback sensors, combined with multi-position analog-to-digital converters, deliver high resolution to meet the demands for rapid scanning and high-precision positioning in optical inspection and related fields.
4. In spectrometers: Rotary voice coil motors drive the rotation of gratings or monochromators to precisely select specific wavelengths, enabling high-precision detection of material composition. By precisely controlling the grating rotation angle, the diffraction angle of light is altered, allowing different wavelengths to accurately focus onto the detector.
Astronomical Telescopes: In astronomical telescopes, rotary voice coil motors enable rapid mirror deflection control. This compensates for factors like atmospheric turbulence that affect observation quality, thereby enhancing the telescope's observational precision.
