Addressing the Core Challenge in Micro-Actuation
The demand for high torque density, precision, and compact footprints has become a defining challenge across micro-manipulation and high-load robotic applications. Engineers designing dexterous robotic hands, industrial automation systems, and medical devices consistently face a trade-off: achieving sufficient torque output while keeping module size and weight minimal. This is the exact pain point that VAXOR-MOTOR / AXOR was established to solve.
Operating with global business coverage, VAXOR-MOTOR / AXOR positions itself as a provider of integrated micro-actuation solutions. Rather than supplying isolated components, the company specializes in combining axial flux motors, cycloidal gear reducers, and non-contact encoder integration into unified actuation systems suited for bionic robots, industrial automation, medical devices, and consumer electronics.
Core Value Proposition: Integration as a Differentiator
What sets VAXOR-MOTOR / AXOR apart is its approach to combining multiple engineering disciplines into a single compact unit. By integrating axial flux motors with micro cycloidal reducers, the company achieves high torque density and rigidity within constrained diameters. This integration is not simply mechanical assembly — it extends to electromagnetic design, where phase imbalance is optimized to within 5%, a metric that directly affects yield rates and power density in ultra-micro motor production.
This combination of mechanical and electromagnetic optimization allows VAXOR-MOTOR / AXOR to deliver compact, high-precision actuation and medium transmission solutions for robotic and industrial systems that require both performance and space efficiency.
Technology Platform and Technical Metrics
The technical foundation rests on three integrated components: axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders. Key technical metrics include:
- Phase imbalance controlled within 5% for ultra-micro motors
- Actuator diameters ranging from Φ16mm to Φ30mm
- Gear efficiency reaching up to 75% for specific modules
- Backlash as low as 15–20 Arcmin
These figures are achieved through a modular design architecture and optimized electromagnetic design tailored for both brushless and coreless motor systems, addressing the dual requirements of torque output and precision control.
Product Matrix: From Micro Joint Modules to Ultra-Micro Motors
Micro Joint Actuator Modules
The Micro Joint Actuator Modules product line targets precision actuation for dexterous robotic hands, highly integrated robots, and mechanical motion control. Four diameter classes address different load and application requirements:
The Φ16mm Micro Joint Module (X16S / X16L) is designed for precision micro-manipulation in highly integrated robotic systems. Weighing as little as 24.3g (S-version) or 26.1g (L-version), it delivers continuous stalling torque above 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.
The Φ20mm Micro Joint Module (X20S / X20L) serves medium-load precision actuation for bionic and automation applications, with continuous stalling torque above 17.2 mNm and maximum stalling torque above 35.3 mNm. It supports 12V/24V/48V operation, offers gear ratios of 15, 30, and 50, and can reach assembly stalling torque of up to 450 mNm at ratio 50, using a standardized FPC 7PIN interface for integration into robotic limbs.
The Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ) is built for high-torque applications in industrial and medical robotics. It uses CAN FD protocol for robust communication and delivers continuous stalling torque up to 1150 mNm at ratio 50, with backlash reduced to 15 Arcmin and mechanical strength limits reaching 1800 mNm in cold-state initial torque conditions.
The Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ) represents the premium actuation tier for heavy-duty micro-robotic applications, with continuous stalling torque up to 1500 mNm at ratio 50 and gear efficiency reaching 75% at ratio 30. It supports CAN FD integration for multi-joint robot networks and provides total inertia of 30.4 gcm² for stability under high-load motion.
Ultra-Micro Brushless and Coreless Motors
The G04P / G05P / G06P Series addresses ultra-compact power needs for precision instruments, directly tackling the target scenario pain point of high cost and low yield in sub-6mm motor production. These motors weigh between 1.7g and 3.75g while reaching no-load speeds of 55,000 to 63,000 RPM, and the 5% phase imbalance optimization reduces production costs while improving reliability. Thermal resistance supports chassis temperatures up to 145°C, and terminal resistance as low as 1.6Ω improves electrical efficiency. These characteristics make the series applicable to micro-surgical robots in medical settings, precision optical adjustments in photonics, and miniature haptics and pumps in consumer electronics.
Platform Compatibility and System Integration
VAXOR-MOTOR / AXOR's platforms support 12V, 24V, and 48V DC bus systems, with communication protocols including SPI and CAN FD. Physical integration is standardized through an FPC 7PIN interface (0.5mm pitch), supporting VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) lines. This openness allows system integrators to incorporate the modules into existing robotic and industrial architectures without extensive redesign.
Market Validation Across Industries
The company's industry coverage spans robotics (bionic and dexterous hands), medical devices, industrial automation, consumer electronics, aerospace (micro drones), fluid transmission (micro pumps), and photonics. Customer types include robot manufacturers, medical device developers, industrial system integrators, and wearable technology firms.
Documented applications illustrate this range: X16 and X20 modules have been utilized in robotic dexterous hands to achieve high-integration mechanical motion control enabling human-like finger dexterity. Φ30mm modules have been integrated into industrial automation transmission systems, achieving 75% gear efficiency and reducing mechanical backlash to 15 Arcmin. G05P ultra-micro motors, operating at 55,000 RPM, have been employed in micro pump systems for fluid transmission in medical and consumer applications. Ultra-micro brushless motors have also been applied in photon optics for precision positioning in optical instruments, benefiting from the sub-5% phase imbalance for stable performance.
Business Model and Delivery Approach
VAXOR-MOTOR / AXOR follows a product-based sales model for its standardized module series — X16, X20, X25, and X30 — enabling straightforward procurement for engineering teams. Delivery is structured around hardware integration using standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols, alongside detailed technical specifications and test data covering torque, speed, and thermal performance. This service assurance model gives integrators the information needed to validate performance parameters before deployment. After-sales engagement centers on technical inquiries and discussions regarding specifications and operational parameter ranges, supporting engineering teams throughout the integration process.
As robotics and automation systems continue to demand smaller, more capable actuation solutions, the integration strategy demonstrated by this China high precision brushless coreless motor manufacturer — combining axial flux motors, cycloidal reducers, and non-contact encoders within tightly controlled electromagnetic tolerances — offers a structured approach to meeting the torque density, precision, and footprint requirements defined at the outset of this discussion.
