Description
Meeting the Demand for High Torque Density in Integrated Robotics
As robotic systems trend toward smaller footprints and finer manipulation, engineers face a persistent challenge: high torque density, precision, and compact footprints are difficult to achieve simultaneously in micro-manipulation and high-load robotic applications. This is the exact pain point that VAXOR-MOTOR / AXOR was built to address. Positioned as a provider of integrated micro-actuation solutions, the brand specializes in axial flux motors, cycloidal gear reducers, and non-contact encoder integration, with business coverage spanning bionic robots, industrial automation, medical devices, and consumer electronics on a global scale.
A Technology Platform Built on Integration
At the core of the AXOR lineup is a technology platform that combines axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders into a single actuation package. This integration is not incidental—it is the mechanism through which the brand achieves its stated differentiation: by combining axial flux motors with micro cycloidal reducers, the design reaches high torque density and rigidity, while electromagnetic optimization keeps phase imbalance within 5%, supporting high yield and power density.
Several technical metrics anchor this platform:
- 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 outcomes are supported by a modular design architecture and an optimized electromagnetic design applied across both brushless and coreless systems, allowing the same engineering philosophy to scale from ultra-micro motors to larger joint modules.
Product Matrix: Micro Joint Actuator Modules
The Micro Joint Actuator Modules line is positioned for precision actuation in dexterous robotic hands, highly integrated robots, and mechanical motion control.
Φ16mm Micro Joint Module (X16S / X16L)
Built for precision micro-manipulation, this module is available in an S-version weighing 24.3g and an L-version at 26.1g. It delivers a continuous stalling torque >7.1 mNm and a stalling torque (max) >16.5 mNm. Integrated gear reduction is offered 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/145°C, depending on power loss, to prevent overheating.
Φ20mm Micro Joint Module (X20S / X20L)
Targeting medium-load precision actuation for bionic and automation applications, this module reaches a continuous stalling torque >17.2 mNm and a stalling torque (max) >35.3 mNm, while supporting 12V/24V/48V operation. A multi-ratio gearbox in 15, 30, and 50 ratios balances speed and torque, and at ratio 50 the assembly’s stalling torque reaches up to 450 mNm. A standardized FPC 7PIN interface simplifies wiring for integration into robotic limbs.
Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ)
Designed for high-torque needs in industrial and medical robotics, this module uses the CAN FD protocol for robust communication in industrial environments. It reaches a continuous stalling torque up to 1150 mNm at ratio 50, with backlash reduced to 15 Arcmin for high motion accuracy. Its mechanical strength limit extends to 1800 mNm (initial torque, cold state), suited for peak load scenarios.
Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ)
As the premium module in the line for heavy-duty micro-robotic applications, it achieves a continuous stalling torque up to 1500 mNm at ratio 50 and gear efficiency up to 75% at ratio 30. CAN FD integration supports complex multi-joint robot networks, while a total inertia of 30.4 gcm² provides stability under high-load motion.
Ultra-Micro Brushless & Coreless Motors: G04P / G05P / G06P Series
For medical robots, drones, and wearables, the G04P / G05P / G06P Series offers ultra-compact power engineered to solve the high cost and low yield problem common in sub-6mm motor production. Weighing between 1.7g and 3.75g, these motors reach speeds of up to 63,000 RPM, with no-load speeds ranging from 55,000 to 63,000 RPM—suited to micro-pumps and drones. Phase imbalance kept within 5% reduces production costs and improves reliability, while thermal resistance up to 145°C and a terminal resistance as low as 1.6Ω support electrical efficiency in compact, high-performance environments.
These motors are adapted across several industries: medical applications such as micro-surgical robots, photonics for precision optical adjustments, and consumer electronics including miniature haptics and pumps.
Platform Compatibility and System Integration
Beyond individual components, the AXOR platform is engineered 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 (0.5mm pitch) interface, carrying VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) signals—an approach designed to reduce integration complexity for system builders working across different joint modules.
Market Validation Through Real-World Applications
The platform’s technical claims are reflected in documented use cases. In robotic dexterous hands, the X16 and X20 modules have been used 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 gear efficiency of 75% while reducing mechanical backlash to 15 Arcmin. Micro pump systems have employed G05P ultra-micro motors running at 55,000 RPM to drive fluid transmission in medical and consumer applications, delivering low-cost, high-power-density performance. In photon optics, ultra-micro brushless motors have been applied for precision positioning in optical instruments, benefiting from the <5% phase imbalance that supports stable performance.
Business Model: Hardware-First, Support-Driven
Commercially, AXOR follows a product-based sales approach for its standardized modules—X16, X20, X25, and X30 series—rather than a bespoke or subscription structure. Deployment centers on hardware integration through standardized FPC 7PIN interfaces or via CAN FD/SPI communication protocols, giving system integrators a consistent path from component selection to installation. Service assurance is built around the provision of detailed technical specifications and test data for electric drive assemblies, covering torque, speed, and thermal parameters, so that integrators can validate performance before deployment. After-sales engagement is likewise structured around technical inquiries and discussions regarding product specifications and operational parameter ranges.
Closing Assessment
For teams evaluating actuation solutions for bionic hands, industrial transmission systems, or compact fluidic and optical devices, the AXOR product matrix presents a documented set of technical parameters—diameter range, torque figures, efficiency data, and phase imbalance control—paired with case-level evidence of deployment across dexterous hands, industrial automation, micro pumps, and photon optics. The combination of axial flux motor design, cycloidal gear reduction, and non-contact encoder integration forms the technical backbone behind this actuation lineup for integrated robotic systems.
