High Precision And Short Response Time Voice Coil Actuator Level Linear Platform
The design principle of the linear platform for voice coil motors is based on the working principle of voice coil motors, combined with mechanical structure and control system to achieve precise linear motion control. The following is the basic principle and concept of designing a linear platform for voice coil motors:
1. Voice coil motor working principle: Voice coil motor is a linear motor composed of a fixed magnetic field and a movable coil. When energized through the coil, the generated current and magnetic field interact to generate a force that drives the coil to move linearly on the guide rail.
2. Mechanical Structure Design: When designing a linear platform for voice coil motors, it is necessary to consider the design of mechanical components such as guides, coils, and motion transmission structures. The guide rail and slider must have high precision, low friction, and high rigidity to ensure smooth movement.
3. Closed structure: To prevent external particles and environmental impacts, a closed mechanical structure can be considered in the design to ensure the protection and stable operation of motor components.
4. Sensor Installation: Install position sensors, such as encoders or Hall sensors, on a linear platform to obtain real-time position feedback. These feedback signals are used in closed-loop control to adjust the movement of the motor and achieve precise position control.
5. Closed loop control system: Voice coil motor linear platforms usually use a closed loop control system, which adjusts the motor's current based on real-time position feedback to accurately move the coil to the target position. The controller can be embedded or external, and can be selected according to application requirements.
