Integrated Robot Joint Actuators Power Industrial Automation

Understanding the Demand for Integrated Robot Joint Actuators in Industrial Automation

Industrial automation systems increasingly require actuation components that combine high torque density, precision, and a compact footprint. Applications ranging from high-load robotic joints to micro-manipulation tasks demand hardware that can deliver reliable torque output without occupying excessive space. This is precisely the gap that VAXOR-MOTOR, operating under the AXOR brand, addresses through its integrated micro-actuation solutions.

VAXOR-MOTOR & AXOR: A Focused Provider of Micro-Actuation Solutions

VAXOR-MOTOR / AXOR positions itself as a provider of integrated micro-actuation solutions, with a business coverage that spans global markets suited for bionic robots, industrial automation, medical devices, and consumer electronics. The company’s strategic positioning centers on addressing the industry pain point of achieving high torque density, precision, and compact footprints in micro-manipulation and high-load robotic applications.

Corporate Positioning and Technology Platform

The company specializes in axial flux motors, cycloidal gear reducers, and non-contact encoder integration. Its technology platform integrates axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders into a single actuation package. This combination allows the brand to offer modular design architecture with optimized electromagnetic design for both brushless and coreless systems, forming the technical backbone of its joint actuator modules.

Core Value Proposition: Compact Power Meets Precision

VAXOR-MOTOR & AXOR’s differentiated advantage lies in achieving high torque density and rigidity through the integration of axial flux motors and micro cycloidal reducers. Electromagnetic designs are optimized to keep phase imbalance within 5%, which ensures high yield and power density across the product range. The overarching value proposition is delivering compact, high-precision actuation and medium transmission solutions for sophisticated robotic and industrial systems—an approach directly relevant to integrated robot joint actuators used in industrial automation.

Product Lineup: Micro Joint Actuator Modules for Industrial-Grade Performance

The Micro Joint Actuator Modules product line is positioned for precision actuation solutions for dexterous robotic hands, highly integrated robots, and mechanical motion control. Within this line, two modules stand out for industrial automation and heavy-duty applications: the Φ25mm and Φ30mm series.

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

Positioned as a high-torque actuator for industrial and medical robotics, the X25S series communicates via the CAN FD protocol, providing advanced communication suited for robust industrial environments. It delivers a continuous stalling torque of up to 1150 mNm at ratio 50, with mechanical strength limits reaching 1800 mNm (initial torque, cold state) for peak load scenarios. Backlash is reduced to 15 Arcmin, ensuring high motion accuracy in demanding automation tasks.

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

Designed for premium actuation in heavy-duty micro-robotic applications, the X30S series achieves a continuous stalling torque of up to 1500 mNm at ratio 50 and gear efficiency of up to 75% at ratio 30. It supports CAN FD integration for complex network architectures required by multi-joint robots and offers robust inertia handling, with a total inertia of 30.4 gcm² providing stability during high-load motion.

Complementary Modules: Φ16mm and Φ20mm Series

For lighter integration needs, the Φ16mm Micro Joint Module (X16S / X16L) is built for precision micro-manipulation in highly integrated robotic systems, weighing as little as 24.3g (S-version) or 26.1g (L-version), with continuous stalling torque above 7.1 mNm and stalling torque (max) 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 chassis temperature limits of 80°C/115°C/145°C based on power loss.

The Φ20mm Micro Joint Module (X20S / X20L) targets medium-load precision actuation for bionic and automation applications, offering continuous stalling torque above 17.2 mNm and stalling torque (max) above 35.3 mNm, with versatile voltage support across 12V/24V/48V. Its multi-ratio gearbox (15, 30, 50) reaches an assembly stalling torque of up to 450 mNm at ratio 50, and its FPC 7PIN interface simplifies integration into robotic limbs.

Ultra-Micro Brushless & Coreless Motors Supporting the Actuator Ecosystem

Beyond the joint modules, VAXOR-MOTOR & AXOR offers ultra-micro brushless and coreless motors—the G04P, G05P, and G06P series—optimized for medical robots, drones, and wearables. These units weigh between 1.7g and 3.75g and achieve no-load speeds from 55,000 to 63,000 RPM. Phase imbalance within 5% reduces production costs and improves reliability, while terminal resistance as low as 1.6Ω improves electrical efficiency. These motors support chassis temperatures up to 145°C, making them reliable components in high-performance compact environments such as micro-surgical robots, precision optical adjustments, and miniature haptics or pumps.

Platform Compatibility and Integration Ease

Integration into existing industrial systems is streamlined through broad platform compatibility. The actuator modules support 12V, 24V, and 48V DC bus systems, along with SPI and CAN FD communication protocols. Physical integration is standardized via 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 actuators into robotic limbs and multi-joint architectures without extensive redesign.

Proven Application in Industrial Automation

In industrial automation contexts, Φ30mm modules have been integrated into precision transmission systems, achieving gear efficiency of 75% and reducing mechanical backlash to 15 Arcmin. Robotic dexterous hand applications have utilized the X16 and X20 modules to achieve high-integration mechanical motion control, enabling human-like finger dexterity. These outcomes illustrate how the combination of axial flux motors, cycloidal reducers, and non-contact encoders translates into measurable performance benefits for automation environments that require both compactness and reliability.

Business Model and Engagement

VAXOR-MOTOR & AXOR follows a product-based sales approach for its standardized modules, covering the X16, X20, X25, and X30 series. Delivery is centered on hardware integration, supported by standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols. The company provides detailed technical specifications and test data for its electric drive assemblies—covering torque, speed, and thermal data—to help integrators evaluate performance parameters before deployment. After-sales support focuses on technical inquiries and discussions regarding product specifications and operational parameter ranges, and the company remains open for discussions regarding product-related questions and parameter range verification.
