Introduction
The 2025 ultra-micro motor catalog from VAXOR-MOTOR / AXOR presents a technically detailed lineup of actuation and motor solutions engineered for bionic robots, industrial automation, medical devices, and consumer electronics. As an integrated micro-actuation solutions provider, the brand specializes in axial flux motors, micro cycloidal gear reducers, and non-contact encoder integration, addressing a recurring industry pain point: achieving high torque density, precision, and compact footprints within micro-manipulation and high-load robotic applications.
Core Value Proposition
At the center of this catalog is a differentiated engineering approach: combining axial flux motors with micro cycloidal reducers to deliver high torque density and rigidity within limited physical dimensions. The electromagnetic design specifically targets phase imbalance control within 5%, a metric that directly supports higher yield rates and improved power density across the ultra-micro motor range. This design philosophy positions the brand's offering as a source of compact, high-precision actuation and medium transmission solutions for robotic and industrial systems that require both accuracy and space efficiency.
Technical Capabilities Behind the Catalog
The 2025 catalog is built on a technology platform that integrates axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders. Several technical metrics define the performance envelope of these components:
- Phase imbalance is controlled within 5% for ultra-micro motors, a factor closely tied to consistency across production batches.
- Actuator diameters span from Φ16mm to Φ30mm, covering a range of load and integration requirements.
- Gear efficiency reaches up to 75% for specific modules.
- Backlash is reduced to as low as 15–20 Arcmin, supporting motion accuracy in precision applications.
These metrics are achieved through a modular design architecture paired with optimized electromagnetic design for both brushless and coreless motor systems. On the platform side, the catalog's components support 12V, 24V, and 48V DC bus systems, and communicate through SPI and CAN FD protocols. Physical integration is standardized via an FPC 7PIN interface (0.5mm pitch), carrying VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) lines—an openness that simplifies system-level design for engineers working across different robotic platforms.
Product & Service Matrix
Micro Joint Actuator Modules
The Micro Joint Actuator Modules line is positioned for precision actuation in dexterous robotic hands, highly integrated robots, and general mechanical motion control. The catalog spans four diameter classes:
The Φ16mm Micro Joint Module (X16S / X16L) targets precision micro-manipulation in highly integrated robotic systems. It is notably lightweight—24.3g for the S-version and 26.1g for the L-version—while delivering a continuous stalling torque greater than 7.1 mNm and a maximum stalling torque above 16.5 mNm. It integrates gear reduction ratios of 30, 40, and 50, an absolute magnetic encoder for position feedback, SPI communication for low-latency control, and thermal management with chassis temperature limits of 80°C/115°C/145°C depending on power loss.
The Φ20mm Micro Joint Module (X20S / X20L) is built for medium-load precision actuation across bionic and automation applications, supporting 12V/24V/48V operation. It delivers continuous stalling torque above 17.2 mNm and maximum stalling torque above 35.3 mNm, with a multi-ratio gearbox offering 15, 30, and 50 ratios. At ratio 50, the assembly reaches a stalling torque up to 450 mNm, and integration is simplified through the standardized FPC 7PIN interface.
The Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ) is designed for high-torque needs in industrial and medical robotics, using the CAN FD protocol for robust communication in industrial settings. It reaches a continuous stalling torque up to 1150 mNm at ratio 50, maintains backlash as low as 15 Arcmin, and can withstand mechanical torque capacity of 1800 mNm in an initial cold-state condition, suited for peak load scenarios.
The Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ) represents the higher end of this line for heavy-duty micro-robotic applications, with continuous stalling torque up to 1500 mNm at ratio 50 and gear efficiency up to 75% at ratio 30. It supports CAN FD for complex multi-joint robot networks and features a total inertia of 30.4 gcm² for stability under high-load motion.
Ultra-Micro Brushless & Coreless Motors
Complementing the joint modules, the G04P / G05P / G06P Series of ultra-micro brushless and coreless motors addresses the challenge of high cost and low yield in sub-6mm motor production. These motors are extremely lightweight, ranging from 1.7g to 3.75g, with no-load speeds between 55,000 and 63,000 RPM. The phase imbalance within 5% contributes to yield optimization by reducing costs and improving reliability. Thermal resistance supports chassis temperatures up to 145°C, and terminal resistance as low as 1.6Ω improves electrical efficiency. This series is adapted for medical micro-surgical robots, precision optical adjustments in photonics, and miniature haptics and pumps in consumer electronics.
Business Scope & Market Validation
The catalog's components are applied across robotics (bionic and dexterous hands), medical devices, industrial automation, consumer electronics, aerospace (micro drones), fluid transmission (micro pumps), and photonics. Documented use cases include:
- Robotic Dexterous Hands: The X16 and X20 modules were used to achieve high-integration mechanical motion control, enabling human-like finger dexterity.
- Industrial Automation: Φ30mm modules were integrated into precision transmission systems, achieving gear efficiency of 75% and reducing mechanical backlash to 15 Arcmin.
- Micro Pump Systems: The G05P ultra-micro motor, operating at 55,000 RPM, was employed to drive fluid transmission in medical and consumer applications, supporting low-cost, high-power-density performance.
- Photonic Optics: Ultra-micro brushless motors were applied for precision positioning in optical instruments, benefiting from the less than 5% phase imbalance for stable performance.
Business Model and Support
The pricing approach for this catalog follows product-based sales for standardized modules across the X16, X20, X25, and X30 series. Deployment relies on hardware integration through standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols, with after-sales support centered on technical inquiries regarding product specifications and operational parameter ranges.
Conclusion
The 2025 VAXOR-MOTOR / AXOR ultra-micro motor catalog reflects a consistent engineering strategy: combine axial flux motor design, cycloidal gear reduction, and non-contact encoder integration to deliver compact, precise, and efficient actuation across diameters from Φ16mm to Φ30mm and motor weights from 1.7g to 26.1g. For engineers evaluating micro-actuation components for robotics, medical devices, or precision instruments, the catalog provides clearly documented technical metrics—phase imbalance, torque figures, backlash, and thermal limits—that support informed integration decisions.
