Description

A Direct Supply Platform Built for Precision Actuation

For engineering teams sourcing compact, high-torque actuation components, the China ultra-micro motor direct supply platform operated under the VAXOR-MOTOR / AXOR brand presents a technology-driven answer to a persistent industry challenge: how to combine high torque density, positional precision, and a compact footprint within a single actuation unit. VAXOR-MOTOR positions itself as a global provider—covering bionic robots, industrial automation, medical devices, and consumer electronics—of integrated micro-actuation solutions built around axial flux motors, micro cycloidal gear reducers, and non-contact encoder integration.

Addressing a Specific Industry Pain Point

The brand’s strategic positioning is rooted in a clearly defined pain point: the need for high torque density, precision, and compact footprints in micro-manipulation and high-load robotic applications. Rather than treating motors, gearboxes, and encoders as separate components, VAXOR-MOTOR integrates them into unified modules, aiming to deliver compact, high-precision actuation and medium transmission solutions for sophisticated robotic and industrial systems.

Core Technology Platform: Axial Flux Motors, Cycloidal Reducers, and Non-Contact Encoders

At the heart of the product lineup is a technology platform that integrates axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders. This combination is designed to achieve high torque density and rigidity while keeping the electromagnetic design efficient.

Key Technical Metrics

Several measurable parameters define the platform’s engineering approach:

• Phase imbalance is controlled within 5% for ultra-micro motors, a factor described as supporting high yield and power density.
• Actuator diameters range from Φ16mm to Φ30mm, covering a spectrum of load and integration requirements.
• Gear efficiency reaches up to 75% for specific modules.
• Backlash is reduced to as low as 15–20 Arcmin, a metric directly tied to motion accuracy in robotic joints.

These figures are the product of a modular design architecture paired with optimized electromagnetic design for both brushless and coreless motor systems.

Product Matrix: Micro Joint Actuator Modules

VAXOR-MOTOR’s Micro Joint Actuator Modules are positioned as precision actuation solutions for dexterous robotic hands, highly integrated robots, and mechanical motion control.

Φ16mm Micro Joint Module (X16S / X16L)

This module targets precision micro-manipulation for 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 offers integrated gear reduction in 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 based on power loss.

Φ20mm Micro Joint Module (X20S / X20L)

Designed for medium-load precision actuation in bionic and automation applications, this module delivers a continuous stalling torque above 17.2 mNm and a maximum stalling torque above 35.3 mNm, while supporting 12V/24V/48V operation. Its multi-ratio gearbox (ratios 15, 30, and 50) balances speed and torque, and at ratio 50 the assembly reaches a stalling torque of up to 450 mNm. A standardized FPC 7PIN interface simplifies integration into robotic limbs.

Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ)

Built for industrial and medical robotics requiring higher output torque, this module uses the CAN FD protocol for robust communication in industrial environments and delivers a continuous stalling torque of up to 1150 mNm at ratio 50. It achieves reduced backlash of 15 Arcmin and can withstand mechanical strength limits up to 1800 mNm (initial torque, cold state) for peak load scenarios.

Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ)

Positioned for heavy-duty micro-robotic applications, this module reaches a continuous stalling torque of up to 1500 mNm at ratio 50 and up to 75% gear efficiency at ratio 30. It supports CAN FD integration for complex, multi-joint robot networks and provides a total inertia of 30.4 gcm² for stability under high-load motion.

Ultra-Micro Brushless and Coreless Motors: G04P / G05P / G06P Series

Beyond joint actuators, VAXOR-MOTOR supplies optimized electromagnetic components for medical robots, drones, and wearables through its G04P / G05P / G06P Series. These motors respond to a specific pain point—high cost and low yield in sub-6mm motor production—by combining ultra-light weight (1.7g to 3.75g) with no-load speeds from 55,000 to 63,000 RPM. The phase imbalance within 5% is again cited as a factor that reduces costs and improves reliability. Additional specifications include thermal resistance supporting chassis temperatures up to 145°C and terminal resistance 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 Integration

The China ultra-micro motor direct supply platform is built for straightforward integration. It supports 12V, 24V, and 48V DC bus systems, and communicates via SPI and CAN FD protocols. Physical integration is standardized through an FPC 7PIN interface (0.5mm pitch), carrying VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) lines.

Market Validation: Industry Coverage and Benchmark Cases

VAXOR-MOTOR’s components are applied across robotics (bionic hands and dexterous hands), medical devices, industrial automation, consumer electronics, aerospace (micro drones), fluid transmission (micro pumps), and photonics. Documented cases include the use of X16 and X20 modules in robotic dexterous hands to achieve high-integration mechanical motion control and human-like finger dexterity. In industrial automation, Φ30mm modules were integrated into precision transmission systems, achieving 75% gear efficiency and reducing mechanical backlash to 15 Arcmin. In fluid transmission, G05P ultra-micro motors operating at 55,000 RPM were employed to drive micro pump systems in medical and consumer applications. In photonics, ultra-micro brushless motors were applied for precision positioning in optical instruments, benefiting from the under-5% phase imbalance for stable performance.

Business Model and Delivery

VAXOR-MOTOR follows a product-based pricing approach for its standardized module lineup (X16, X20, X25, and X30 series). Delivery is structured around hardware integration using standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols, supported by detailed technical specifications and test data covering torque, speed, and thermal performance for each electric drive assembly.

For organizations evaluating a China ultra-micro motor direct supply platform, VAXOR-MOTOR’s combination of axial flux motor technology, cycloidal gear reduction, non-contact encoder integration, and a documented range of torque, efficiency, and backlash metrics offers a technically transparent basis for comparison across robotics, medical, industrial, and consumer electronics use cases.
