Hollow-rotor voice coil motors are commonly used in the autofocus systems of smartphone cameras to enable autofocus and optical image stabilization.
In autofocus systems, the hollow-rotor motor drives the lens group to move back and forth along the optical axis to achieve focus.
Thanks to the motor’s high response speed and precise control, the camera can quickly and accurately focus on the subject.
Additionally, in optical image stabilization systems, hollow voice coil motors compensate for camera shake by rapidly adjusting the lens position, thereby enhancing image clarity.
Hollow motors are directly integrated into the autofocus systems of smart cameras. By precisely controlling the lens position, they enable fast, high-precision focusing, ensuring sharp images.
Hollow motors are compact and lightweight, making them suitable for the confined spaces inside smartphones while also reducing the overall weight of the device.
With their high-speed response and microsecond-level adjustment capabilities, hollow voice coil motors meet the stringent requirements of smart camera photography for instantaneous focusing and fine-tuning.
Type: Hollow-coil motors, hollow-core motors.
Features: Fast response, high acceleration, lightweight coils, no cogging effect, zero hysteresis, simple structure, lightweight, high-frequency response, and smooth operation.
Applications: Widely used in optical scanning, positioning, and automatic alignment systems. Modular design, customizable.
