High Accuracy Rotary Voice Coil Motor Moving Coil Actuator For Focusing Lens Slider
New Voice Coil Motor For Focusing Lens Slider High-Accuracy High Frequency
The use of swing type new voice coil motors in focusing lenses usually involves achieving precise adjustment of the focusing lens to change the focal length and focus of the beam. The following is the general usage method of the swing type new voice coil motor in the focusing lens:
1. Motor installation: Install the swing type new voice coil motor on the mechanical structure connected to the focusing lens. Ensure that the connection between the motor and the lens is secure.
2. Lens Support Structure: Ensure that the focusing lens is installed on a support structure that allows the lens to undergo small rotational or oscillating movements under the control of the motor.
3. Circuit connection: Connect the coil of the motor to the control circuit. This control circuit can control the current based on the input signal, thereby controlling the rotation or oscillation of the motor.
4. Sensor installation (optional): If closed-loop control and precise feedback are required, a position sensor or angle encoder can be installed between the motor and the lens to monitor the actual position of the lens.
5. Control System: Establish a control system that can control the rotation or oscillation of the motor by inputting control signals. This can be a microcontroller or computer based system.
6. Motion Control: Adjust the control signal according to actual needs to control the rotation or swing angle of the motor. This can cause slight changes in the position of the lens.
7. Focusing adjustment: By controlling the movement of the motor, minor adjustments are made to the focusing lens. This can change the focal length of the beam, thereby changing the focal point of the beam.
8. Real time feedback (optional): If a sensor is installed, the position of the lens can be monitored in real-time and adjusted as needed to achieve more precise focus control.
