In the world of precision optics, semiconductor testing, laser applications and advanced research, even a slight deviation in any angle can lead to experimental failure, product defects or data distortion. How to achieve precise and stable rotational positioning with no margin of error is the core challenge that countless engineers and researchers are striving to overcome. After 20 years of deep research in the field of precision optical machinery, Sevan Optoelectronics, with its profound technical foundation, has meticulously developed the 7SRA series closed-loop electric rotary table, integrating sub-degree-level closed-loop accuracy, zero-gap transmission and extremely strong rigidity bearing, providing a perfect solution for high-precision angle control.
I. Closed-loop servo, sub-degree precision: meticulous and precise
The core of Saifan Optoelectronics' closed-loop electric rotating platform lies in its fully closed-loop real-time feedback control system, which fundamentally eliminates the cumulative errors and drift of open-loop control.
Ultra-high resolution grating feedback: Equipped with a high-precision circular grating encoder with a resolution of up to 0.0001° (0.36 degrees), it can capture every tiny rotation angle of the platform in real time and rapidly feed back the signal to the drive system.
Ultra-precise positioning: By using closed-loop servo algorithms to dynamically correct deviations, the repeat positioning accuracy can reach ±0.5 degrees, and the absolute positioning accuracy, after compensation, can reach ±1 degree (customized models are higher). Whether it is the precise alignment of optical components, the precise adjustment of optical path angles, or the angular resolution testing of samples, it can achieve "pointing and rotating exactly where needed" with absolute precision.
Wide speed range, suitable for both static and dynamic applications: The speed range covers 0.0001°/s to 25°/s. The ultra-low speed is smooth without creep, meeting the needs of precise scanning; the high-speed positioning is swift, significantly improving the efficiency of experiments and tests.
II. Precise machinery, zero-gap stability: Rock-solid stability
Precision stems from stability. The mechanical structure of Saifan's rotating platform has undergone countless trials and tests to ensure smooth movement and long-term reliability.
Precision gears and zero backlash transmission: Using precision grinding-grade worm gears and worm wheels, combined with a unique backlash elimination structure, the return stroke gap is completely eliminated. There is no jamming or deviation when reversing, ensuring consistent positioning in the full range.
Cross cylindrical roller bearings, high rigidity bearing capacity: The core shaft system uses cross cylindrical roller bearings, which can withstand radial, axial, and overturning torques. The platform surface jump is less than 0.04mm, with a bearing capacity of up to 50kg. Even under heavy loads, it remains as stable as a rock, with an extremely perfect rotational concentricity.
Sturdy and durable, long-life design: The main body is made of high-strength aluminum alloy, precisely processed and surface hard anodized, wear-resistant and corrosion-resistant. The core components have a long lifespan, and daily maintenance is simple, allowing for stable operation in harsh environments for many years.
III. Flexible design, all-around compatibility: Seamless integration of efficiency
Saifan's closed-loop rotating platform is designed with modular and highly compatible features, easily adapting to various scenarios and ready for immediate use.
Multi-scenario installation: Compact structure, supporting horizontal, vertical, and inverted installation methods, perfectly meeting the layout requirements for complex optical paths and space-constrained environments.
Standard electrical control, convenient control: Standard high-performance stepper motors and standard communication interfaces are provided, directly compatible with the 7SC series motion controller, supporting various control modes such as computer programming, manual control panel, etc., to easily achieve 360° continuous rotation, angle stepping, and reciprocating scanning for complex movements.
Standard center hole, practical and thoughtful: The platform design features a standard center hole, facilitating the passage of optical fibers, cables, and airflow, perfectly solving practical problems such as optical path routing and multi-workstation integration.
