Spiro Gear
As the global industrial landscape transitions toward automation, robotics, and high-efficiency electrification, the demand for precision motion control has reached a critical juncture. Planetary gearbox motors—characterized by their coaxial design and load-sharing between multiple planet gears—offer the highest power density among all gear reduction systems. At Spiro Gear, we don't just manufacture motors; we engineer the "mechanical heart" of modern innovation.
The market for micro-drive systems is expanding rapidly, driven by AI-integrated robotics and renewable energy. Current industrial benchmarks require motors to achieve 90%+ efficiency while maintaining a footprint smaller than 40mm. Our planetary systems are engineered to meet these rigorous torque-to-weight ratios.
Direct-from-factory sourcing in China has evolved. It is no longer about "low cost," but about "optimized supply chain resilience." By integrating R&D, CNC machining, and automated assembly in-house, we reduce lead times by 30% compared to traditional trading companies.
20+ Years of Manufacturing Integrity & Precision Engineering
Deep industry heritage ensuring stable automated production lines and long-term supply security. Our engineers understand the nuances of gear meshing and material fatigue.
100% In-House Loading Tests: Every single motor is subjected to automated dynamic balancing and acoustic tests under real industrial loads before leaving our dock.
Our state-of-the-art ecology runs fully compliant with international ISO9001, CE, RoHS, and REACH safety standards. Zero-defect performance is our baseline.
We rapidly customize shafts, integrated encoders, and specialized gearheads to fit your device housing perfectly. We embrace non-standard blueprints.

Soundproof RoomAs a leading China Planetary Gearbox Motor Factory, our R&D roadmap focuses on four core technological advancements:
Transitioning from basic encoders to integrated AI-ready sensors that provide real-time data on temperature, vibration, and torque load, facilitating predictive maintenance.
Utilizing advanced polymer-metal hybrid gears for ultra-low noise applications in medical and smart-home environments, reducing decibel levels by up to 15dB.
Development of specialized lubricants and coatings that allow motors to operate in temperatures ranging from -40°C to +125°C, suitable for aerospace and outdoor automotive use.
Engineering 10mm-16mm planetary gearheads that deliver the same torque as traditional 28mm units, essential for the next wave of wearable exoskeletons.
Precision motion across every border and every sector
Providing the smooth, jitter-free movement required for robotic-assisted surgery and high-precision diagnostic equipment.
Optimized for charging pile locks, seat adjustment systems, and active aerodynamic components in EVs.
Low-noise planetary motors for smart curtains, locks, and pet feeders, ensuring longevity and user comfort.
High-torque reduction for automated guided vehicles and warehouse logistics robots operating 24/7.
Planetary gears distribute the load across several planet gears, allowing them to handle significantly higher torque in a more compact volume. They also offer higher efficiency and better coaxial alignment.
We use high-precision CNC hobbing machines (Ningjiang) and automated gear riveting. Every motor undergoes a dynamometer test and noise analysis to ensure it matches the golden sample's performance curve.
Yes. Our "Agile Custom Prototyping" program allows for rapid modification of D-cut shafts, cross-holes, specialized flange mounts, and custom lead-wire connectors.
All our products are fully compliant with RoHS and REACH environmental standards, and we hold CE and ISO9001:2015 certifications to ensure global regulatory acceptance.
Standard samples can be delivered within 7-10 days, while full-scale mass production orders typically range from 3-5 weeks depending on the complexity of customization.
