For engineers designing dexterous robotic hands, medical instruments, micro drones, or industrial automation systems, the search for a reliable source of ultra micro brushless and coreless motors often runs into the same obstacles: limited torque density, inconsistent yield, and a lack of integrated actuation solutions that fit compact footprints. VAXOR-MOTOR, operating under the brand AXOR, addresses this gap as a global provider of integrated micro-actuation solutions, specializing in axial flux motors, cycloidal gear reducers, and non-contact encoder integration.

Corporate Positioning and Industry Focus

VAXOR-MOTOR / AXOR serves a global business scope suited for bionic robots, industrial automation, medical devices, and consumer electronics. The company’s strategic positioning centers on an industry pain point insight: 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 that combine motor, reducer, and sensing technology into unified modules.

Core Technology Platform

At the center of VAXOR-MOTOR’s value proposition is the integration of 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 optimizing electromagnetic performance.

A defining technical metric is phase imbalance control within 5% for ultra-micro motors. This level of electromagnetic optimization is intended to ensure high yield and power density, particularly important for manufacturers producing sub-6mm motors where cost and reliability are closely tied to production consistency. Additional technical benchmarks include actuator diameters ranging from Φ16mm to Φ30mm, gear efficiency reaching up to 75% for specific modules, and backlash as low as 15-20 Arcmin. These figures reflect a modular design architecture built on optimized electromagnetic design for both brushless and coreless systems.

Micro Joint Actuator Modules

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

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

The Φ20mm Micro Joint Module (X20S / X20L) is built for medium-load precision actuation in bionic and automation applications. It supports 12V, 24V, and 48V operation and offers continuous stalling torque above 17.2 mNm with a maximum stalling torque above 35.3 mNm. A multi-ratio gearbox with 15, 30, and 50 ratio options allows the assembly to reach stalling torque up to 450 mNm at ratio 50, while an FPC 7PIN interface standardizes wiring for power and data.

The Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ) is designed for high-torque applications in industrial and medical robotics, using the CAN FD protocol for robust communication in industrial environments. It reaches continuous stalling torque up to 1150 mNm at ratio 50, with reduced backlash of 15 Arcmin and a mechanical strength limit of 1800 mNm initial torque in a cold state.

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 up to 75% at ratio 30. Total inertia of 30.4 gcm² supports stability during high-load motion, and CAN FD integration enables complex network architectures for multi-joint robots.

Ultra-Micro Brushless and Coreless Motors

Alongside the joint modules, VAXOR-MOTOR offers the G04P, G05P, and G06P series of ultra-micro brushless and coreless motors, positioned as optimized electromagnetic components for medical robots, drones, and wearables. These motors respond directly to the target scenario pain point of high cost and low yield in sub-6mm motor production.

The series is ultra-lightweight, ranging from 1.7g to 3.75g, with no-load speeds from 55,000 to 63,000 RPM, making it suited for micro-pumps and drones. Phase imbalance is controlled within 5%, which is described as reducing costs and improving reliability through yield optimization. Chassis temperatures up to 145°C are supported for thermal resistance, and terminal resistance as low as 1.6Ω contributes to electrical efficiency. Industry adaptation spans 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 platform is built for compatibility across common industrial power architectures, supporting 12V, 24V, and 48V DC bus systems. Communication is handled through SPI and CAN FD protocols, while physical integration relies on an FPC 7PIN interface with 0.5mm pitch, carrying VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) lines. This openness is intended to simplify integration into robotic limbs and multi-joint systems without requiring proprietary wiring standards.

Validated Applications

Several benchmark scenarios illustrate how VAXOR-MOTOR’s product matrix has been applied. In robotic dexterous hands, X16 and X20 modules have been used to achieve high-integration mechanical motion control, supporting human-like finger dexterity. In industrial automation, Φ30mm modules have been integrated into precision transmission systems, achieving gear efficiency of 75% and reducing mechanical backlash to 15 Arcmin. In micro pump systems, G05P ultra-micro motors operating at 55,000 RPM have driven fluid transmission for medical and consumer applications, emphasizing low-cost and high-power density. In photon optics, ultra-micro brushless motors have supported precision positioning in optical instruments, benefiting from the phase imbalance below 5% for stable performance.

Business Model and Support

VAXOR-MOTOR operates on a product-based sales model for its standardized modules across the X16, X20, X25, and X30 series. Deployment follows hardware integration paths using standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols. After-sales engagement centers on technical inquiries and discussions regarding product specifications and operational parameter ranges, along with provision of detailed technical specifications and test data covering torque, speed, and thermal performance for electric drive assemblies.

For robot manufacturers, medical device developers, industrial system integrators, and wearable technology firms evaluating actuation and motor solutions, VAXOR-MOTOR’s combination of axial flux motor design, cycloidal gear reduction, non-contact encoder integration, and standardized communication interfaces offers a structured framework for comparing compact, high-precision actuation options against project-specific torque, speed, and footprint requirements.
