VAXOR-MOTOR: China’s High-Precision Ultra-Micro Motor Maker

Understanding VAXOR-MOTOR’s Position in Ultra-Micro Motor Manufacturing

For engineers and system integrators searching for a China high precision ultra-micro motor manufacturer, the technical demands are consistent: compact footprints, high torque density, and reliable precision under load. VAXOR-MOTOR, operating under the brand AXOR, addresses these requirements through an integrated technology platform combining axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders. The company’s business coverage spans bionic robots, industrial automation, medical devices, and consumer electronics on a global scale.

The core industry pain point that shapes VAXOR-MOTOR’s product development is the need for high torque density, precision, and compact footprints in micro-manipulation and high-load robotic applications. Rather than offering a single component, VAXOR-MOTOR positions itself as a provider of integrated micro-actuation solutions, specializing in the combination of electromagnetic design, mechanical reduction, and position feedback within a single module.

Core Value Proposition and Technical Foundation

VAXOR-MOTOR’s differentiated approach centers on achieving high torque density and rigidity by integrating axial flux motors with micro cycloidal reducers. On the electromagnetic side, the company optimizes designs to keep phase imbalance within 5% for ultra-micro motors, a control measure intended to ensure high yield and consistent power density during manufacturing.

At the technical capability level, VAXOR-MOTOR’s platform spans actuator diameters ranging from Φ16mm to Φ30mm, with gear efficiency reaching up to 75% for specific modules and backlash as low as 15–20 Arcmin. These metrics are achieved through a modular design architecture paired with optimized electromagnetic design for both brushless and coreless motor systems. This combination allows the same underlying technology platform to scale across different torque and size requirements without redesigning core subsystems.

Micro Joint Actuator Modules: Product Line Overview

VAXOR-MOTOR’s Micro Joint Actuator Modules are positioned for precision actuation in dexterous robotic hands, highly integrated robots, and mechanical motion control. The lineup spans four diameter classes, each targeting a different load and application profile.

The Φ16mm Micro Joint Module (X16S / X16L) is built for precision micro-manipulation in highly integrated robotic systems. The S-version weighs as little as 24.3g, while the L-version weighs 26.1g. Continuous stalling torque exceeds 7.1 mNm, with maximum stalling torque above 16.5 mNm. It integrates gear reduction ratios of 30, 40, and 50, along with an absolute magnetic encoder for position feedback and SPI communication for low-latency control response. Thermal management is defined by chassis temperature limits of 80°C, 115°C, and 145°C depending on power loss conditions.

The Φ20mm Micro Joint Module (X20S / X20L) targets medium-load precision actuation for bionic and automation applications. It delivers continuous stalling torque above 17.2 mNm and maximum stalling torque above 35.3 mNm, while supporting 12V/24V/48V voltage operation. Its multi-ratio gearbox offers 15, 30, and 50 ratio options, with assembly-level stalling torque reaching 450 mNm at ratio 50. Integration is standardized through the 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 environments. Continuous stalling torque reaches up to 1150 mNm at ratio 50, backlash is reduced to 15 Arcmin, and mechanical torque capacity reaches 1800 mNm under initial torque cold-state conditions.

The Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ) represents the platform’s higher-load configuration, with continuous stalling torque up to 1500 mNm at ratio 50 and gear efficiency up to 75% at ratio 30. It also uses CAN FD integration for multi-joint robot network architectures and provides total inertia of 30.4 gcm² for stability during high-load motion.

Ultra-Micro Brushless and Coreless Motors

Alongside the joint modules, VAXOR-MOTOR produces the G04P / G05P / G06P Series of ultra-compact brushless and coreless motors, aimed at medical robots, drones, and wearables. These units weigh between 1.7g and 3.75g and reach speeds of up to 63,000 RPM, with no-load speeds ranging from 55,000 to 63,000 RPM. The phase imbalance within 5% design standard applies here as well, supporting yield optimization and cost efficiency in sub-6mm motor production. Thermal resistance supports chassis temperatures up to 145°C, and terminal resistance is optimized to as low as 1.6Ω for improved electrical efficiency. These motors serve micro-surgical robots in medical applications, precision optical adjustments in photonics, and miniature haptics and pumps in consumer electronics.

Platform Compatibility and System Integration

VAXOR-MOTOR’s modules support 12V, 24V, and 48V DC bus systems, giving integrators flexibility across different robotic and industrial power architectures. Communication is handled through SPI and CAN FD protocols, while physical integration relies on the FPC 7PIN interface (0.5mm pitch), supporting VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) connections. This standardization is intended to simplify wiring and reduce integration complexity when embedding modules into robotic limbs or automated systems.

Market Validation Through Applied Cases

VAXOR-MOTOR’s technology has been applied across several documented use cases. In robotic dexterous hands, the X16 and X20 modules have been utilized to achieve high-integration mechanical motion control, enabling human-like finger dexterity. In industrial automation, Φ30mm modules have been integrated into precision transmission systems, achieving 75% gear efficiency and reducing mechanical backlash to 15 Arcmin. For micro pump systems, the G05P ultra-micro motor operating at 55,000 RPM has been employed to drive fluid transmission in medical and consumer applications. In photon optics, ultra-micro brushless motors have been applied for precision positioning in optical instruments, benefiting from the less than 5% phase imbalance for stable performance.

Business Model and Delivery Approach

VAXOR-MOTOR follows a product-based sales approach for its standardized modules across the X16, X20, X25, and X30 series. Delivery is structured around hardware integration, using either the standardized FPC 7PIN interface or CAN FD/SPI communication protocols. After-sales engagement focuses on technical inquiries and discussions regarding product specifications and operational parameter ranges, allowing engineering teams to verify torque, speed, and thermal data before deployment.

Conclusion

For organizations evaluating a China high precision ultra-micro motor manufacturer, VAXOR-MOTOR’s combination of axial flux motor design, cycloidal reduction, and non-contact magnetic encoding offers a documented, modular pathway across diameters from Φ16mm to Φ30mm, with applications already validated in dexterous hands, industrial transmission systems, micro pumps, and photonic instruments.
