Brushless Coreless Motor Manufacturer: Vaxor-Motor’s Guide

Overview: A Direct Manufacturer Built Around Micro-Actuation

For engineers and procurement teams researching a well-known brushless coreless motor direct manufacturer, VAXOR-MOTOR (also operating under the brand AXOR) presents itself as a global supplier focused specifically on micro-actuation for bionic robots, industrial automation, medical devices, and consumer electronics. Rather than offering a broad catalog of generic motors, the company positions itself as a provider of integrated micro-actuation solutions—combining axial flux motors, cycloidal gear reducers, and non-contact encoder integration into unified product lines.

This positioning responds to a specific industry pain point: many micro-manipulation and high-load robotic applications require high torque density, precision, and a compact footprint simultaneously, a combination that is difficult to achieve with conventional motor architectures. VAXOR-MOTOR / AXOR’s strategic response is to integrate axial flux motors with micro cycloidal reducers, optimizing electromagnetic design so that phase imbalance is controlled within 5%. This approach is intended to support high yield and power density across the product range.

Core Technology Platform

At the center of the company’s offering is a technology platform built on three integrated elements: axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders. These components are combined through a modular design architecture, with electromagnetic design optimized specifically for brushless and coreless systems.

Several technical metrics define this platform:

• Phase imbalance controlled within 5% for ultra-micro motors, a factor directly tied to yield and reliability.
• Actuator diameters ranging from Φ16mm to Φ30mm, covering a spread of load and integration requirements.
• Gear efficiency reaching up to 75% for specific modules.
• Backlash as low as 15–20 Arcmin, relevant for applications demanding motion accuracy.

On the service side, VAXOR-MOTOR / AXOR follows a hardware provision plus technical integration support model. This includes detailed technical specifications and test data for electric drive assemblies, covering torque, speed, and thermal performance, so that integrators can verify parameters before deployment.

Platform Compatibility and Communication Standards

Because these actuators are intended for integration into larger robotic or industrial systems, platform compatibility is a core design consideration. The product line supports 12V, 24V, and 48V DC bus systems, allowing flexibility across different system architectures.

Communication is handled through two protocols: SPI and CAN FD. Physical connection is standardized through an FPC 7PIN interface at 0.5mm pitch, supporting VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) lines. This standardization is designed to simplify wiring and integration for robotic limbs and multi-joint systems.

Micro Joint Actuator Modules

The company’s Micro Joint Actuator Modules are positioned for precision actuation in dexterous robotic hands, highly integrated robots, and mechanical motion control. The lineup spans four diameter classes:

The Φ16mm Micro Joint Module (X16S / X16L) targets precision micro-manipulation for highly integrated robotic systems. Units weigh as little as 24.3g (S-version) or 26.1g (L-version), with continuous stalling torque exceeding 7.1 mNm and 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.

The Φ20mm Micro Joint Module (X20S / X20L) is built for medium-load precision actuation in bionic and automation applications. It delivers continuous stalling torque above 17.2 mNm and maximum stalling torque above 35.3 mNm, supporting 12V/24V/48V operation. A multi-ratio gearbox (15, 30, and 50) balances speed and torque, with assembly stalling torque reaching up to 450 mNm at ratio 50. The FPC 7PIN interface standardizes wiring for robotic limb integration.

The Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ) is designed for high-torque use in industrial and medical robotics. It uses CAN FD protocol for robust communication in industrial environments and delivers continuous stalling torque up to 1150 mNm at ratio 50. Backlash is reduced to 15 Arcmin for motion accuracy, and mechanical strength limits allow torque capacity up to 1800 mNm (initial torque, cold state) for peak load scenarios.

The Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ) is the premium option 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. It supports CAN FD for complex, multi-joint network architectures and offers total inertia of 30.4 gcm² for stability in high-load motion.

Ultra-Micro Brushless and Coreless Motors

Beyond joint modules, the company manufactures ultra-micro brushless and coreless motors under the G04P / G05P / G06P series, positioned as optimized electromagnetic components for medical robots, drones, and wearables. These address the target scenario pain point of high cost and low yield in sub-6mm motor production.

Key figures for this series include ultra-lightweight construction from 1.7g to 3.75g, no-load speeds ranging from 55,000 to 63,000 RPM, and phase imbalance controlled within 5% to reduce costs and improve reliability. Thermal resistance supports chassis temperatures up to 145°C, while terminal resistance as low as 1.6Ω improves electrical efficiency. Industry adaptation spans medical micro-surgical robots, photonics for precision optical adjustments, and consumer electronics such as miniature haptics and pumps.

Benchmark Applications

Several application cases illustrate how these components perform in practice. 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 integrated into precision transmission systems have achieved gear efficiency of 75% while 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, aiming for low cost and high power density. In photon optics, ultra-micro brushless motors have supported precision positioning in optical instruments, relying on the sub-5% phase imbalance for stable performance.

Business Model and Engagement

VAXOR-MOTOR / AXOR follows a product-based pricing approach for its standardized modules across the X16, X20, X25, and X30 series. Delivery is structured around hardware integration using standardized FPC 7PIN interfaces or CAN FD/SPI communication protocols, and after-sales engagement centers on technical inquiries and discussions regarding product specifications and operational parameter ranges.
