Tesla Optimus Supply Chain Analysis: Moons' Strategic Role in Motion Control and Mini Actuators

MOONS’ (Shanghai Moons’ Electric) is emerging as a strategically important motion-control supplier for the global humanoid-robotics wave, with increasing relevance to Tesla’s Optimus program. Known globally for high-precision stepper motors, hollow-cup motors, and compact motion controllers, the company is now positioning itself at the fine-motion and dexterous-hand layer of humanoid systems. While Tesla-related EV revenue remains unconfirmed, MOONS’ hollow-cup motors and motion-control modules have reportedly passed early Optimus qualification, targeting potential mass supply as the robot scales. With manufacturing in China and Vietnam, strong export capability, and deep motion-control IP, MOONS’ is becoming a notable candidate in Tesla’s humanoid supply chain.

1. Company Snapshot — From Stepper Motors to Strategic Robotics Player

MOONS’ (Shanghai Moons’ Electric, SH603728) is a global motion-control and intelligent LED driver manufacturer founded in 1994. It is widely ranked among the world’s top three hybrid stepper-motor makers, shipping over 10 million units annually. As of late November 2025, its market capitalization is around CNY 27–30 billion (roughly USD 3.7–4.0 billion). H1 2025 revenue reached CNY 1.31 billion with net profit of CNY 27 million. The company has about 3,500 employees and generates more than 40% of its sales overseas.

3. Relationship with Tesla EV and Optimus

Public information does not clearly confirm large-scale MOONS’ content in Tesla EVs; any seat/aux-motor usage remains undisclosed. The strategic connection is on the humanoid-robotics side. Since 2023, MOONS’ has reportedly been supplying 10 mm brushless hollow-cup motor samples (e.g., ECH10032 series) for Optimus dexterous-hand prototypes and has passed Tesla’s “C-round” qualification as a quasi-supplier, with mass supply targeted for 2026 if Optimus scales. Some brokerage commentary suggests MOONS’ motion controllers already account for over 40% of Optimus joint-controller sourcing in testing phases, though this is unconfirmed by Tesla. Revenue impact remains limited in 2025 but represents significant option value.

4. Humanoid Robotics Role, Capacity Readiness and Competitive Edge

In the Optimus architecture, MOONS’ sits at the fine-motion and dexterous-joint layer—high-speed hollow-cup motors and compact motion controllers for fingers, wrists, and micro-joints where power density and responsiveness are critical. Its Taicang and Vietnam factories give it scalable, export-friendly capacity, while overseas acquisitions strengthen sales channels in North America and Europe. If Optimus scales into high-volume deployment, MOONS’ could evolve from a niche motor supplier into a significant actuator-and-control provider for humanoid robots globally—though outcomes depend on Tesla’s actual ramp-up speed and MOONS’ ability to maintain precision yields at scale.
