A hollow-core voice coil motor is a specialized type of voice coil motor characterized by an internal through-hole structure, a design that provides greater flexibility and adaptability in applications.
It features rapid response, high precision, lightweight construction, and the ability to be modularized.
Applications of Hollow-Core Motors in Optical Systems:
Cameras and Digital Cameras: Used to enable autofocus functionality. By precisely controlling the movement of the voice coil motor, the distance between the lens and the imaging element is adjusted quickly and accurately, ensuring a clear image.
Microscopes: Enhances the microscope’s autofocus capability, allowing users to quickly locate a clear field of view and improving observation efficiency and accuracy—which is crucial for the observation and study of microscopic objects.
High response, high acceleration, low mass coils.
No cogging effect, zero hysteresis.
Simple structure, light weight, high frequency response.
