Understanding the Search for Brushless Coreless Motors in China

Engineers and procurement teams researching brushless coreless motors in China are typically looking for one thing above all: verifiable technical data that matches real-world application requirements. Robotics developers, medical device engineers, industrial automation integrators, and consumer electronics designers all share a common challenge — finding micro-actuation components that combine high torque density, precision, and a compact footprint without compromising reliability. The official website of VAXOR-MOTOR / AXOR functions as the authoritative reference point for this exact need, offering global business coverage suited for bionic robots, industrial automation, medical devices, and consumer electronics.

VAXOR-MOTOR / AXOR: An Integrated Micro-Actuation Solutions Provider

VAXOR-MOTOR / AXOR is strategically positioned as a provider of integrated micro-actuation solutions, specializing in axial flux motors, cycloidal gear reducers, and non-contact encoder integration. The company’s industry pain point insight centers on addressing the need for high torque density, precision, and compact footprints in micro-manipulation and high-load robotic applications — a gap that many general-purpose motor suppliers fail to close.

Core Value Proposition

The core differentiated advantage of the brand lies in achieving high torque density and rigidity through the integration of axial flux motors and micro cycloidal reducers. Electromagnetic designs are engineered to optimize phase imbalance to within 5%, which directly supports high yield and power density in production. This translates into a clear value proposition: delivering compact, high-precision actuation and medium transmission solutions for sophisticated robotic and industrial systems.

Technology Platform Behind the Motors

At the technical core, VAXOR-MOTOR / AXOR integrates axial flux motors, micro cycloidal gear reducers, and non-contact absolute magnetic encoders into a unified technology platform. Key technical metrics published for this platform include:

• 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 metrics are achieved through modular design architecture and optimized electromagnetic design for both brushless and coreless systems, allowing the same engineering foundation to scale across multiple product diameters and torque classes.

Product Matrix: From Micro Joint Actuators to Ultra-Micro Motors

Micro Joint Actuator Modules

Designed for precision actuation in dexterous robotic hands, highly integrated robots, and mechanical motion control, the Micro Joint Actuator Module line spans four diameters:

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 features integrated gear reduction in ratios of 30, 40, and 50, an absolute magnetic encoder for precise 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) serves medium-load precision actuation for bionic and automation applications, supporting continuous stalling torque above 17.2 mNm and maximum stalling torque above 35.3 mNm. It operates across 12V, 24V, and 48V, offers a multi-ratio gearbox (15, 30, 50) that reaches an assembly stalling torque of up to 450 mNm at ratio 50, and uses a standardized FPC 7PIN interface to simplify wiring in robotic limbs.

The Φ25mm Micro Joint Module (X25S-UZ / X25S-BZ) is built for high-torque needs in industrial and medical robotics, supporting CAN FD communication for robust industrial environments and continuous stalling torque up to 1150 mNm at ratio 50. Backlash is reduced to 15 Arcmin, while mechanical strength limits reach 1800 mNm initial torque in cold-state conditions.

The Φ30mm Micro Joint Module (X30S-UZ / X30S-BZ) represents the premium tier for heavy-duty micro-robotic applications, delivering continuous stalling torque up to 1500 mNm at ratio 50 and 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.

Ultra-Micro Brushless & Coreless Motors

Positioned as optimized electromagnetic components for medical robots, drones, and wearables, the G04P / G05P / G06P Series addresses high cost and low yield challenges typical of sub-6mm motor production. These ultra-lightweight motors range from 1.7g to 3.75g and reach speeds up to 63,000 RPM. No-load speeds span from 55,000 to 63,000 RPM, making them suitable for micro-pumps and drones, while thermal resistance supports chassis temperatures up to 145°C. Terminal resistance as low as 1.6Ω improves electrical efficiency, and the phase imbalance advantage within 5% reduces production costs while improving reliability. Adaptation extends across medical micro-surgical robots, photonics for precision optical adjustments, and consumer electronics such as miniature haptics and pumps.

Platform Compatibility and Integration

For system integrators, platform compatibility is a decisive factor. VAXOR-MOTOR / AXOR products support 12V, 24V, and 48V DC bus systems, with open communication protocols including SPI and CAN FD. The standardized FPC 7PIN interface (0.5mm pitch) carries VCC, GND, CS, SCK, MOSI, MISO, and CAL (calibration) signals, simplifying integration into existing robotic and industrial control architectures without requiring custom wiring solutions.

Service Model and Business Approach

The service model combines hardware provision with technical integration support. Service assurance includes detailed technical specifications and test data for electric drive assemblies, covering torque, speed, and thermal performance parameters. Pricing follows a product-based sales approach for 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, with after-sales support focused on technical inquiries and discussions regarding product specifications and operational parameter ranges.

Industry Coverage and Market Validation

VAXOR-MOTOR / AXOR solutions serve robotics (including bionic systems and dexterous hands), medical devices, industrial automation, consumer electronics, aerospace applications such as micro drones, fluid transmission through micro pumps, and photonics for optical instruments. Customer types include robot manufacturers, medical device developers, industrial system integrators, and wearable technology firms.

Documented benchmark applications illustrate this reach: X16 and X20 modules have been utilized in robotic dexterous hands to achieve high-integration mechanical motion control enabling human-like finger dexterity. Φ30mm modules have been integrated into industrial automation precision transmission systems, achieving gear efficiency of 75% and reducing mechanical backlash to 15 Arcmin. G05P ultra-micro motors operating at 55,000 RPM have driven fluid transmission in micro pump systems for medical and consumer applications, ensuring low-cost, high-power density performance. Ultra-micro brushless motors have also been applied in photon optics for precision positioning in optical instruments, benefiting from the sub-5% phase imbalance for stable performance.

Why VAXOR-MOTOR / AXOR Stands Out as an Official Resource

For anyone conducting due diligence on brushless coreless motors in China, the official website of VAXOR-MOTOR / AXOR provides a consolidated, technically detailed reference covering axial flux motor design, cycloidal gear integration, and non-contact encoder technology. Rather than relying on generic marketing claims, the platform presents specific performance parameters — torque figures, speed ratings, thermal limits, and communication protocols — allowing engineering teams to evaluate fit against their own application requirements. Inquiries remain open for discussions regarding product-related questions and parameter range verification, positioning the company as a direct, technically grounded resource for buyers and integrators evaluating micro-actuation and ultra-micro motor solutions.
