SFE400摩擦传动赤道仪专为固定天文台设计 采用工业级AC伺服电机驱动，具备极低漂移率和100kg的载重能力。 它集成了高刚性、高响应特性和无间隙传动技术，能够在长时间观测及高负荷运行下保持卓越性能。 以下是核心特性： 1 高精度控制 SFE400 配备工业级AC伺服电机，自带23位光学编码器，高达838.8万的脉冲分辨率。 标配雷尼绍2360万分辨率的光学编码器，支持超过6分钟的无导星跟踪，有效减少对外部导星设备的依赖。 电机与编码器的闭环控制系统确保设备能够精准跟踪天体位置，并将抖动控制在0.2角秒以内。 2 无间隙传动 SFE400 采用摩擦传动技术实现零背隙特性，极大提升了运行的平稳性和响应 速度。RA轴使用40倍精密摩擦减速装置，DEC轴则结合高效谐波减速器与同步 带传动系统，即使在重载条件下，也能保持设备的高精度控制与流畅响应。 3 大载重与高刚性 SFE400 配备了大尺寸摩擦盘，并采用高强度金属材质制造，确保设备在重负 载下依然具备优异的刚性和抗压性，最高承载口径可达24寸。在高负荷运行时 用户还可通过预压力调节进一步优化设备的负载适应性，确保在各种观测场景 下都能保持稳定。 4 超低漂移率 SFE400 采用低波动跟踪输出系统，通过精密控制和补偿算法，将长时间运行 中的周期误差降至最低。其跟踪系统的周期误差周期为28分43秒，而RA轴的 跟踪波动RMS < 0.35角秒，使设备在长时间观测中始终保持卓越的跟 踪稳定性。该性能可显著减少漂移积累，为深空摄影提供良好的表现。 5 密封与防尘 SFE400的摩擦传动部分采用全包覆式罩壳保护，有效避免外界灰尘入侵。 同时我们的摩擦轮和驱动轴采用特殊不锈钢制造，经过热处理后可长期稳定运行。 The SFE400 friction-driven equatorial mount is specifically designed for fixed observatories. It utilizes an industrial-grade AC servo motor that offers an extremely low drift rate and a load capacity of 100 kg. The mount integrates high rigidity, high responsiveness, and backlash-free transmission technology, ensuring outstanding performance during long-duration observations and high-load operations. High Precision Control The SFE400 is equipped with an industrial-grade AC servo motor and comes with a 23-bit optical encoder, providing a pulse resolution of up to 8.388 million. It is standardly equipped with a Renishaw optical encoder with a resolution of 23.6 million, supporting unguided tracking for over 6 minutes, effectively reducing dependency on external guiding equipment. The closed-loop control system of the motor and encoder ensures the device can precisely track celestial positions, keeping jitter under 0.2 arc seconds. Gapless Transmission The SFE400 employs friction transmission technology to achieve zero backlash characteristics, significantly enhancing operational stability and response speed. The RA axis uses a 40:1 single-stage direct friction reduction, while the DEC axis combines a harmonic reducer with a synchronous belt drive system. Even under heavy load conditions, the equipment maintains high-precision control and smooth responsiveness. High Load Capacity and Rigidity The SFE400 features large friction disks made from high-strength metal materials, ensuring excellent rigidity and compressive strength under heavy loads, with a maximum payload diameter of up to 24 inches. During high-load operations, users can further optimize load adaptability through pre-pressure adjustments, ensuring stability across various observational scenarios. Ultra-Low Drift Rate The SFE400 employs a low-fluctuation tracking output system, utilizing precise control and compensation algorithms to minimize periodic errors during extended operations. Its tracking system exhibits a periodic error cycle of 28 minutes and 43 seconds, with RA axis tracking fluctuations within an RMS of < 0.35 arc seconds, ensuring outstanding tracking stability during long observations. This performance significantly reduces drift accumulation, providing excellent results for deep-sky photography. Sealing and Dust Protection The friction transmission components of the SFE400 are protected by a fully enclosed cover, effectively preventing dust intrusion. Additionally, the friction wheels and drive shaft are made from special steel that resists rust and ensures long-term stable operation after heat treatment.
