Buyers searching for a "high torque ultra-micro motor price list" are typically comparing torque density, footprint, and integration complexity before committing to a supplier. VAXOR-MOTOR (also referred to under the AXOR brand) addresses this search intent not with a simple price sheet, but with a structured product-based sales model built around standardized, technically documented modules. This review examines how the company's Micro Joint Actuator Modules and Ultra-Micro Brushless & Coreless Motors are positioned, what technical data backs their torque claims, and where the product line has been validated in real-world applications.
How VAXOR-MOTOR Structures Its Pricing and Delivery Model
Rather than publishing a generic price list, VAXOR-MOTOR operates on an "Approach: Product-based sales for standardized modules (X16, X20, X25, X30 series)" basis. This means pricing is tied directly to a defined catalog of hardware modules rather than custom quoting for each order. Delivery follows a hardware integration model that relies on standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols, allowing engineering teams to evaluate compatibility before purchase. After-sales engagement is limited to "technical inquiries and discussions regarding product specifications and operational parameter ranges," which keeps the buying process focused on verifiable data rather than negotiation.
Micro Joint Actuator Modules: The Core High-Torque Lineup
The Micro Joint Actuator Modules line is positioned for "precision actuation for dexterous robotic hands, highly integrated robots, and mechanical motion control," and it is here that the high torque density claims are most concentrated.
The Φ16mm Micro Joint Module (X16S / X16L) targets precision micro-manipulation. The S-version weighs as little as 24.3g and the L-version 26.1g, while delivering a continuous stalling torque greater than 7.1 mNm and a maximum stalling torque above 16.5 mNm. It integrates gear reduction ratios of 30, 40, and 50, an absolute magnetic encoder for position feedback, and SPI communication for low-latency control. Thermal management is defined through chassis temperature limits of 80°C, 115°C, and 145°C depending on power loss.
The Φ20mm Micro Joint Module (X20S / X20L) steps up to medium-load applications, supporting 12V, 24V, and 48V operation. It offers a continuous stalling torque above 17.2 mNm and a maximum stalling torque above 35.3 mNm, with gearbox ratios of 15, 30, and 50. At the ratio-50 configuration, the assembled unit reaches a stalling torque of up to 450 mNm, using the same FPC 7PIN interface for simplified wiring into robotic limbs.
For higher-torque industrial and medical use cases, the Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ) adopts CAN FD communication for robust operation in industrial environments. It delivers a continuous stalling torque of up to 1150 mNm at ratio 50, with backlash controlled to 15 Arcmin and a mechanical torque capacity reaching 1800 mNm in the initial, cold-state condition.
At the top of the range, the Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ) is built for heavy-duty micro-robotic applications, reaching a continuous stalling torque of up to 1500 mNm at ratio 50. It achieves gear efficiency of up to 75% at ratio 30, supports CAN FD networking for multi-joint robot architectures, and carries a total inertia of 30.4 gcm² for stable high-load motion.
Ultra-Micro Brushless & Coreless Motors for Precision Instruments
Alongside the actuator modules, VAXOR-MOTOR offers the G04P / G05P / G06P Series of ultra-compact brushless and coreless motors, positioned for "medical robots, drones, and wearables." These units address the target scenario pain point of "high cost and low yield in sub-6mm motor production." Weight ranges from 1.7g to 3.75g, with no-load speeds spanning 55,000 to 63,000 RPM, making them suited to micro-pumps and drone components. A key differentiator is phase imbalance controlled within 5%, which the company states "reduces costs and improves reliability." These motors also support chassis temperatures up to 145°C and feature terminal resistance as low as 1.6Ω for improved electrical efficiency. Industry adaptation spans medical micro-surgical robots, photonics for precision optical adjustments, and consumer electronics such as miniature haptics and pumps.
The Technology Platform Behind the Torque Claims
The torque density and compactness across both product families are rooted in a shared technology platform combining axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders. Electromagnetic designs are optimized to keep phase imbalance within 5% for ultra-micro motors, which the company links to higher yield and power density. Across the actuator range, diameters span Φ16mm to Φ30mm, gear efficiency reaches up to 75% for specific modules, and backlash is reduced to 15–20 Arcmin. Connectivity is standardized through SPI and CAN FD protocols, with a physical FPC 7PIN (0.5mm pitch) interface carrying VCC, GND, CS, SCK, MOSI, MISO, and a dedicated CAL (calibration) line.
Market Validation Through Documented Use Cases
VAXOR-MOTOR's modules have been applied across several documented scenarios. In robotic dexterous hands, the X16 and X20 modules were used to achieve "high-integration mechanical motion control, enabling human-like finger dexterity." In industrial automation, Φ30mm modules were integrated into precision transmission systems, achieving the stated 75% gear efficiency while reducing mechanical backlash to 15 Arcmin. Micro pump systems in medical and consumer applications employed the G05P ultra-micro motor running at 55,000 RPM, valued for its low-cost, high-power-density profile. In photon optics, ultra-micro brushless motors were applied for precision positioning in optical instruments, benefiting from the less than 5% phase imbalance for stable performance.
What This Means for Buyers Comparing Options
For engineering teams evaluating a "price list," the practical takeaway is that VAXOR-MOTOR's value is expressed through documented technical specifications—torque figures, backlash tolerances, thermal limits, and communication protocols—rather than a flat catalog price. Its product-based sales approach across the X16, X20, X25, and X30 series, combined with the G04P/G05P/G06P motor lineup, gives buyers a defined set of modules to match against torque, voltage, and interface requirements across robotics, medical devices, industrial automation, consumer electronics, aerospace micro drones, fluid transmission, and photonics applications.
