特斯拉Optimus机器人供应链拆解（02.09版）

3C供应链02-09

1月28日特斯拉在2025 Q4业绩报告中披露，Optimus Gen3为首个面向量产的设计版本，首条生产线正在推进供应链就绪，计划在2026年底前启动生产，远期规划产能目标为年产100万台。本文围绕特斯拉人形机器人Optimus，系统梳理其整机拆解结构，并按“执行器、传感与电子、结构与机械、电池与电源、外壳与其他”五大模块，对可能涉及的上游供应商进行逐一落位与分级，形成一份可持续更新的供应链清单...

Q4业绩报告中披露，Optimus Gen3为首个面向量产的设计版本，首条生产线正在推进供应链就绪，计划在2026年底前启动生产，远期规划产能目标为年产100万台。本文围绕特斯拉人形机器人Optimus，系统梳理其整机拆解结构，并按“执行器、传感与电子、结构与机械、电池与电源、外壳与其他”五大模块，对可能涉及的上游供应商进行逐一落位与分级，形成一份可持续更新的供应链清单，用于追踪Optimus从研发走向量产过程中，各关键部件与对应供给侧的变化。此次为“持续更新版”供应链底稿：随着后续特斯拉官方披露、供应商公告及权威媒体信息更新，名单与分级将滚动修订。一、供应商分级说明A类（强确认）供应商公告、年报、法说会材料或官方新闻稿中，出现“特斯拉 + 机器人业务 / 人形机器人 / Optimus”同框表述，或特斯拉官方材料点名供应商。B类（中确认）权威媒体或海外投行研究明确指出“进入特斯拉机器人供应链 / 为Optimus提供某类部件”，但尚未看到供应商自身公告层面的同框确认。C类（产业链相关公司）这类公司出现在行业研究报告对“人形机器人产业链”的相关公司列表中，但目前尚无公开信息显示其已进入特斯拉Optimus供应链或获得定点。二、整机成本与结构（全文统一拆解框架）本文按“5大模块”拆解Optimus整机BOM与供应链结构（占比为行业示意区间，用于结构化分析，不等同于特斯拉官方BOM）：1）执行器系统Actuation：约45–50%2）传感器与电子Sensors & Electronics：约30%3）结构与机械Structure & Mechanics：约15%4）电池与电源Battery & Power：约5–10%5）外壳与其他Enclosure & Other：<5%三、执行器系统Actuation（约45–50%）执行器是人形机器人“价值量最高、降本最难、供应链最先收敛”的模块之一：它把电机、减速器/丝杠、传感器、控制器、轴承与结构件集成为可量产的关节/直线驱动总成，直接决定整机负载、速度、寿命与一致性。3.1 结构与成本执行器内部成本结构（取自：前瞻产业研究院）：行星滚柱丝杠PRS：19%无框力矩电机：16%减速器：13%力传感器：11%空心杯电机：8%IMU：2%其他：31%对早期Optimus执行器架构拆解：14个线性执行器（无框电机+丝杠+控制器+轴承等）、14个旋转执行器（无框电机+减速器+控制器+轴承等），灵巧手为11自由度结构（空心杯电机+蜗轮蜗杆+腱绳结构）。3.2 PRS行星滚柱丝杠（19%）PRS（Planetary Roller Screw，行星滚柱丝杠）用于把电机旋转运动高效率转换为直线推拉力，适配腿部等需要“高载荷、长寿命、高频往复与冲击载荷”的直线执行器。对量产而言，关键约束集中在：丝杠材料与热处理窗口、螺纹/滚柱加工一致性、寿命与磨损曲线、装配预紧与间隙控制、批量检测与追溯体系。Fast Company报道指出，Optimus在小腿部位使用4个行星滚柱丝杠。A类暂无。B类新剑传动（来源：LatePost）北特科技（来源：LatePost）恒立液压（来源：券商研报）北特科技在2024年10月披露拟投资18.5亿元建设“行星滚柱丝杠研发生产基地项目”，被解读为围绕人形机器人方向的产能押注与能力建设。C类3.3 无框力矩电机（16%）无框力矩电机把定子/转子融入关节结构，减少外壳与冗余件，提升扭矩密度并缩短传动链，常用于关节直驱或高集成关节。量产门槛主要来自：绝缘可靠性与耐压一致性、温升与散热路径设计、装配同心度与气隙控制、磁材与叠片供应稳定性、驱动参数标定与一致性。A类暂无B类暂无C类科尔摩根Kollmorgen（科尔摩根，美国：无框电机品牌，隶属Regal Rexnord体系）补充说明：卧龙电驱曾在互动平台就“其轴向磁通电机与无框力矩电机进入特斯拉Optimus测试、锁定订单”的市场传闻作出否认回复。3.4 减速器（13%）减速器承担关节端扭矩放大与刚度控制，直接影响关节寿命、噪声、效率和动态控制稳定性。人形机器人常见路线包括谐波减速器与RV/精密行星路线的组合；对量产而言，核心约束在：齿形加工与热处理一致性、背隙与刚度控制、寿命与润滑、噪声曲线、批量检测与良率、以及与电机/编码器/壳体的系统级装配公差链。A类暂无。B类五洲新春（来源：券商产业链调研）C类哈默纳科Harmonic Drive Systems（中文常用名：哈默纳科，日本：谐波减速器）纳博特斯克Nabtesco（中文常用名：纳博特斯克，日本：精密减速器）绿的谐波（中国：谐波减速器平台公司）来源：Morgan Stanley《The Humanoid 100》及行业研究。3.5 力传感器（11%）力/力矩传感器用于把“接触力、支撑力、扭矩”转换为可闭环控制的信号，是人形机器人稳定行走、跌倒恢复、安全交互与精细操作的重要输入之一。典型包括六轴力/力矩传感器（可同时测量XYZ三向力与三向力矩），常见安装在踝/腕/末端执行器等位置。供应链关键点在：多轴解耦与标定体系、长期漂移与温漂控制、批量一致性、过载保护与结构强度、成本曲线（高性能产品单价高，量产降本压力大）。A类暂无B类ATI Industrial Automation（中文常用名：ATI工业自动化，美国：六轴力/力矩传感器；官网明确用于人形机器人踝关节应用）C类Novanta（诺万达，美国：力传感器系统平台）来源：Morgan Stanley《The Humanoid 100》。3.6 空心杯电机（8%）空心杯电机（Coreless DC motor）常用于灵巧手等末端执行器，核心优势是低惯量、响应快、低齿槽效应（或更易实现平滑控制），利于“细腻力控与快速启停”。量产难点集中在：绕组一致性与良率、寿命与噪声曲线、成本曲线、以及与减速/蜗杆/腱绳机构的装配窗口与可靠性。国金拆解明确灵巧手为11自由度，并给出空心杯电机+蜗轮蜗杆+腱绳结构路径，预计第三代会增至22自由度。A类暂无。B类暂无C类鸣志电器MOONS’（中文常用名：鸣志电器/品牌MOONS’，中国：空心杯电机与运动控制）瑞士Maxon（中文常用名：马克森/麦克森，瑞士：精密微电机）来源：行业研究3.7 IMU惯导（2%）IMU（Inertial Measurement Unit，惯性测量单元）通常由陀螺仪与加速度计组成，为姿态估计、行走稳定性与跌倒恢复提供底层状态输入；量产难点常见于标定、装配位置一致性、温漂与长期稳定性、以及与全身控制算法的融合。公开层面特斯拉未点名Optimus IMU供应商。A类暂无。B类暂无。C类暂无。3.8 其他（31%）“其他”覆盖执行器量产落地中最容易被低估、但决定爬坡速度与良率的环节：驱动与功率器件、编码器、轴承导向、结构件、线束连接、测试与标定工装、自动化装配夹具与追溯系统等。对供应链而言，这部分往往决定“同一设计能否批量复制”，并影响执行器从样机到量产的单位成本下降斜率。A类暂无。B类拓普集团Tuopu（拓普集团，中国）和大Hota
