Explore our highly integrated micro stepping motors featuring custom gear ratios, optimized voltage curves, and industry-leading performance-to-size ratios.
At Axon Motor, we believe that global innovation shouldn't be limited by size. For two decades, we have dedicated ourselves to a single, relentless pursuit: designing, engineering, and manufacturing high-performance micro-drive solutions that keep modern industries moving forward. Based in China, we operate a state-of-the-art, ISO9001-certified production facility specializing in Micro DC Motors, DC Gear Motors, and Brushless DC Motors (BLDC), alongside our cutting-edge Permanent Magnet (PM) Stepper Motors.
We understand that applications like smart home automation, medical devices, automotive electronics, and precision robotics demand uncompromised reliability. That is why every Axon Motor micro motor is built with an exceptional power-to-size ratio, ultra-low noise acoustics, and an extended operational lifespan, backed by strict 100% in-house quality control and international certifications (CE, RoHS, REACH).
We don’t just supply standard hardware; we act as a strategic R&D partner. With a robust engineering team holding multiple industry patents, Axon Motor thrives on solving complex mechanical challenges through flexible OEM/ODM custom solutions. From custom shaft configurations and custom voltage tuning to specialized bespoke gearheads, we turn your technical blueprints into high-volume, cost-effective reality.
Permanent Magnet (PM) stepper motors leverage a magnetized cylindrical rotor interacting with electromagnetic stator coils to achieve discrete, highly repeatable angular steps. Understanding the physics behind these motions is critical for high-efficiency design.
By incorporating high-remanence Neodymium (NdFeB) or Samarium Cobalt (SmCo) permanent magnets into the rotor core, our PM stepper motors deliver superior holding torque in micro-enclosures down to 6mm in diameter.
Operating natively with standard step angles such as 7.5° and 18°, these systems allow straightforward open-loop control without the need for complex, failure-prone encoder feedback loops.
By refining slot-pole combinations and implementing microstepping drivers, mechanical vibration and resonance peaks are mitigated, rendering these motors suitable for silent environments like VR headsets and medical diagnostics.
As modern automation demands higher power density, integration, and precision, Axon Motor's technical development follows three core vectors.
| Development Vector | Current Capabilities | Roadmap Targets (2025-2027) | Primary Industrial Drivers |
|---|---|---|---|
| Micro-Miniaturization | Outer diameter boundaries at 6mm - 10mm with custom step angles. | Standardization of 4.5mm diameter stepper motor assemblies. | In-vivo medical tools, wearable AR/VR modules, surgical robotics. |
| Material Optimization | N35UH to N45H NdFeB Magnets, maximum continuous temperature 120°C. | High-temperature SmCo / specialized iron-cobalt core lamination (up to 180°C). | Automotive engine bay actuators, smart grid valves, aerospace devices. |
| Integrated Intelligence | Stand-alone motors requiring external driver and controller hardware. | System-in-Package (SiP) integrated driver, encoder, and CAN/LIN bus nodes. | Decentralized automated guided vehicles (AGV), smart home nodes. |

Answers to standard engineering questions regarding the application and performance limits of micro permanent magnet stepper systems.
PM stepper motors utilize a non-toothed, radially magnetized permanent magnet rotor, which yields a simpler construction, higher inherent holding detent torque without power, and significantly lower manufacturing cost in diameters under 20mm. Hybrid steppers offer higher step resolution but are difficult to manufacture in sub-10mm form factors.
As temperature rises, the remanence (Br) of the internal Neodymium rotor magnet declines, leading to a drop in holding torque. Our specialized windings and optional SmCo magnet integrations allow operational ranges from -40°C up to +120°C (customizable to 150°C+ for critical automotive or defense needs).
Yes. Although micro PM steppers are typically operated in open-loop setups to minimize system volume and cost, we can customize a sub-miniature magnetic or optical encoder on the back shaft (e.g., our 20mm Micro Stepper with Encoder) for applications requiring precise position tracking.
We supply precision plastic planetary gearboxes for low-noise, wearable applications (e.g., VR glasses), metal planetary systems for high-load industrial use, and custom worm gearboxes for self-locking performance in medical dosing pumps.
We follow a rigorous APQP (Advanced Product Quality Planning) process. Every new prototype batch undergoes full dynamic analysis, lifecycle thermal stress testing, and mechanical dimensional audits using our Keyence laser calipers and Vickers hardness testers before tooling sign-off.
Yes. Our manufacturing facilities maintain ISO 9001 and ISO 13485 (Medical Devices Quality Management) compliance. Our raw materials are fully documented with RoHS and REACH certifications, ensuring smooth qualification for clinical markets.
