High Precision Hollow Core Motor Miniature VCM Linear Actuator For Focusing Mobile Phone Cameras

Product Description:

Hollow core motors, also called hollow cup motors or ironless core motors, are often used in cell phone camera focusing systems for autofocus and optical stabilization.
In the autofocus system hollow motor realizes the focusing function by driving the lens group back and forth along the direction of the optical axis.
Utilizing the high response speed and precise control of the motor, the camera is able to focus on the target object quickly and accurately.

Secondly, in the optical stabilization system, the hollow motor quickly adjusts the position of the lens to compensate for the displacement caused by hand shaking, thus improving the clarity of photos.
This is especially important when shooting video or long exposure photos, and can significantly reduce image blur.
Hollow motors are used directly in the autofocus system of cell phone cameras. By accurately controlling the lens position, it realizes a fast, high-precision focusing function that ensures clear shooting images. For example, in dynamic shooting scenarios (e.g., video recording), its low-inertia feature reduces motion artifacts and improves focusing in real time.
The small size and light weight of the hollow motor fits into the compact space inside a cell phone, while reducing the overall load on the machine.
Efficient Response and Control Precision: With its high speed response and microsecond adjustment capability, the motor meets the instantaneous focusing and subtle displacement requirements of cell phone photography, especially in low light or complex lighting conditions.
Low Power Consumption and Low Noise: Its high-efficiency design reduces power loss and extends the life of the phone, and its low operating noise enhances the user experience.
