基于 AS5047 的 14-bit 高分辨率磁编码器，通过电机端与负载端双位协同，消除行星减速器背隙与传动误差，为高负载机器人关节打造高性价比、高可靠性的全闭环运动控制系统。Built on the AS5047 14-bit high-resolution magnetic encoder, this solution uses dual-position collaboration between motor-side and load-side encoders to eliminate planetary gearbox backlash and transmission errors — a cost-effective, high-reliability closed-loop motion control system for high-load robot joints.
针对足部关节负重大的特点，采用行星减速器方案，通过双编算法消除传动背隙（Backlash）与负载扰动。For foot joints bearing heavy loads, a planetary gearbox is combined with a dual-encoder algorithm to eliminate backlash and load disturbances.
摒弃性能过剩的昂贵器件，利用 AS5047 的 14-bit 精度完美匹配行星减速器的机械特性，实现成本与性能的最佳平衡。Avoids over-specified expensive parts; the AS5047's 14-bit precision is matched to the planetary gearbox mechanics for the best cost-performance balance.
依靠 AS5047 的低延迟特性，确保机器人在高频冲击和快速行走中的姿态控制稳定性。The low latency of AS5047 ensures stable pose control for robots under high-frequency impacts and rapid walking.
AS5047 独有的 DAEC™ 技术能补偿高速旋转下的传播延迟。在电机端作为速度环反馈时，即使在急加速或高转速下，也能提供接近零延迟的角度数据，确保机器人的平衡算法能实时响应地面冲击。AS5047's proprietary DAEC™ technology compensates propagation delay at high speeds. As velocity-loop feedback on the motor side, it delivers near-zero-latency angle data even during rapid acceleration or high RPM, so the robot's balance algorithm can respond to ground impact in real time.
基于 AS5047 霍尔传感器阵列的差分传感技术，使方案对外部杂散磁场具有极高的免疫力。在电机强磁场环境下（如紧凑型关节模组），无需复杂的屏蔽措施即可稳定工作。Differential sensing based on the AS5047 Hall sensor array gives the solution high immunity to external stray magnetic fields. It works stably in strong motor magnetic fields — such as compact joint modules — without complex shielding.
电机端利用高刷新率进行高带宽速度控制和换相；负载端利用 14-bit 高分辨率（0.022° 精度）直接读取最终输出角度。即使减速机存在 5–10 弧分的背隙，也能通过负载端直接反馈将静态误差降至最低。The motor side uses a high refresh rate for high-bandwidth speed control and commutation; the load side reads the final output angle directly with 14-bit resolution (0.022° precision). Even with 5–10 arcminutes of gearbox backlash, static error is minimized through direct load-side feedback.
高负载足部与腿部关节，对背隙、冲击和姿态稳定性要求极高，是双编方案最典型的落地点。High-load foot and leg joints with strict requirements on backlash, impact, and pose stability — the most typical use case for dual-encoder solutions.
通过负载端直接反馈补偿减速器与传动机构带来的末端误差，提高重复定位精度。Load-side direct feedback compensates for end-effector errors caused by reducers and transmission mechanisms, improving repeatability.
