Swing Type Voice Coil Motor With Encoder Rotary Voice Coil For Optical Alignment

The swing voice coil motor with optical alignment encoder is a specially designed motor system that combines the swing voice coil motor and optical alignment encoder for precise angle control and positioning. This type of motor system is usually used in applications that require high-precision positioning and angle adjustment, especially in fields such as optical equipment, imaging systems, and precision instruments.
The swinging voice coil motor serves as the driving component to drive rotational motion by generating Lorentz force. The optical alignment encoder is a sensor that can measure angles or positions, providing accurate angle feedback by monitoring changes in optical signals.
The swinging voice coil motor with combined optical alignment encoder has the following characteristics:
1. High precision positioning: The optical alignment encoder can provide very accurate angle measurement, enabling the motor to achieve high-precision angle positioning.
2. Real time feedback: The real-time feedback of the optical alignment encoder allows the control system to monitor the position of the motor in real time, thereby achieving closed-loop control and making the motor's movement more accurate and stable.
3. Quick Response: The swinging voice coil motor has fast responsiveness, combined with high-precision feedback from optical alignment encoders, to achieve fast and accurate angle adjustment.
4. Smooth motion: The combination of the smooth motion characteristics of the swinging voice coil motor and the precise measurement of the optical alignment encoder can achieve smooth angular motion.
5. Contactless Design: The optical alignment encoder is a contactless sensor that has no mechanical contact with motor components, reducing friction and wear.
6. Wide application range: The swing type voice coil motor with optical alignment encoder is suitable for various applications that require high-precision angle control and positioning, including optical equipment, laser systems, telescopes, imaging equipment, etc.

Applications:

Rotary Voice Coil Motor (VCM) is a kind of arc voice coil motor, which has the characteristics of high acceleration, high response frequency, short response time and high accuracy. Swing type series can produce torque more than 100NM, swing torque more than 90 degrees, this kind of motor is especially suitable for small stroke high precision and high response frequency system can do high-speed oscillating back and forth motion. Voice coil motor is a non-commutation type power device, its positioning accuracy completely depends on the feedback and control system, has nothing to do with voice coil motor itself. The positioning accuracy can easily reach 10nm and the acceleration can reach 300g (the actual acceleration depends on the specific working condition of the load) . Swing-type products are typically used in laser technology in the mirror locator, valve brakes, automation equipment, aerospace, semiconductor and other industrial fields.
