AXOR Supplier Guide

Introduction: Why Ultra-Micro Motor Selection Matters

Choosing the right ultra-micro motor supplier is a critical decision for engineering teams working on bionic robots, industrial automation systems, medical devices, and consumer electronics. The core challenge lies in balancing torque density, precision, and compact footprint requirements—especially for micro-manipulation and high-load robotic applications. This guide examines how VAXOR-MOTOR, operating under the brand AXOR, addresses these industry pain points through an integrated micro-actuation technology platform.

Understanding the Industry Pain Point

Sub-6mm motor production has historically faced high production costs and low manufacturing yield, which directly affects the affordability and reliability of downstream robotic and medical device applications. VAXOR-MOTOR positions itself as a provider of integrated micro-actuation solutions, specializing in axial flux motors, cycloidal gear reducers, and non-contact encoder integration—directly targeting this need for high torque density, precision, and compact footprints.

Core Technology Platform

VAXOR-MOTOR’s differentiated advantage comes from the integration of axial flux motors and micro cycloidal reducers, which together achieve high torque density and rigidity. The electromagnetic design is optimized to control phase imbalance within 5%, a factor that directly supports high yield and power density during production.

Key technical metrics that buyers should evaluate when comparing ultra-micro motor suppliers include:

• Phase imbalance: controlled within 5% for ultra-micro motors, supporting manufacturing yield and cost efficiency.
• Actuator diameter range: from Φ16mm to Φ30mm, covering a wide span of joint and actuation needs.
• Gear efficiency: reaching up to 75% for specific modules.
• Backlash: as low as 15–20 Arcmin, a key factor for motion accuracy in precision robotics.

These metrics are achieved through a modular design architecture and optimized electromagnetic design for both brushless and coreless systems, giving engineering teams flexibility across different application requirements.

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. The lineup spans four diameter classes, each targeting distinct load and integration scenarios.

Φ16mm Micro Joint Module (X16S / X16L)

Designed for precision micro-manipulation in highly integrated robotic systems, this module is notably lightweight—24.3g for the S-version and 26.1g for the L-version. 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, 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, or 145°C depending on power loss.

Φ20mm Micro Joint Module (X20S / X20L)

Built for medium-load precision actuation in bionic and automation applications, this module delivers continuous stalling torque above 17.2 mNm and maximum stalling torque above 35.3 mNm. It supports 12V, 24V, and 48V operation, and offers gearbox ratios of 15, 30, and 50—reaching stalling torque of up to 450 mNm at ratio 50. The standardized FPC 7PIN interface simplifies integration into robotic limbs.

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

Targeted at industrial and medical robotics requiring higher output torque, this module uses 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 strength limits allow torque capacity up to 1800 mNm under initial cold-state conditions.

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

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

Product Matrix: Ultra-Micro Brushless & Coreless Motors

The G04P / G05P / G06P Series addresses the specific pain point of high cost and low yield in sub-6mm motor production. These motors are ultra-lightweight, ranging from 1.7g to 3.75g, with no-load speeds between 55,000 and 63,000 RPM. Phase imbalance is controlled within 5%, directly supporting cost reduction and reliability improvement. Chassis temperature resistance reaches up to 145°C, and terminal resistance as low as 1.6Ω improves electrical efficiency. This series is adapted for medical micro-surgical robots, photonics applications requiring precision optical adjustment, and consumer electronics such as miniature haptics and pumps.

Platform Compatibility and Integration

For buyers evaluating supplier compatibility with existing systems, VAXOR-MOTOR’s platform supports 12V, 24V, and 48V DC bus systems. Communication protocols include SPI and CAN FD, and the standardized interface is an FPC 7PIN connector with 0.5mm pitch, supporting VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) lines. This level of openness allows engineering teams to integrate modules into existing robotic and automation architectures without extensive redesign.

Validated Applications Across Industries

VAXOR-MOTOR’s technology has been applied across several benchmark scenarios. In robotic dexterous hands, 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% 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 with low-cost, high-power density performance. In photonics, ultra-micro brushless motors have been applied for precision positioning in optical instruments, benefiting from the sub-5% phase imbalance for stable performance.

Business Model and Support

VAXOR-MOTOR follows a product-based sales approach for its standardized modules across the X16, X20, X25, and X30 series. Deployment relies on hardware integration through standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols. After-sales support covers technical inquiries and discussions regarding product specifications and operational parameter ranges, providing engineering teams with detailed technical specifications and test data covering torque, speed, and thermal performance for each electric drive assembly.

Key Selection Criteria for Buyers

When evaluating ultra-micro motor and micro joint actuator suppliers, engineering and procurement teams should consider:

• Torque requirements: Match continuous and maximum stalling torque figures to the specific joint or actuation load.
• Diameter constraints: Confirm the actuator diameter (Φ16mm to Φ30mm range) fits the mechanical envelope.
• Communication protocol compatibility: Verify whether SPI or CAN FD aligns with the existing control architecture.
• Voltage bus alignment: Confirm compatibility with 12V, 24V, or 48V DC systems.
• Precision needs: Review backlash specifications (15–20 Arcmin) against required motion accuracy.
• Thermal operating range: Check chassis temperature limits relative to the application’s duty cycle.
