Goaxis Pro: Factory-Direct Micro Motors Engineered for Zero-Defect Performance

Tired of trading company markups, communication gaps, and inconsistent batch quality in your motion control supply chain? Goaxis Pro is the transparent, direct-from-source China factory you’ve been looking for. We engineer and manufacture world-class precision micro drives directly from our manufacturing floors to your global assembly lines under strict, repeatable quality control.

Dual shaft configuration offers structural advantages in mechanical design. By providing driving power from both the front and rear extensions of a single motor rotor, engineers can drive primary mechanisms (such as worm gear boxes or driving wheels) from one end, while utilizing the secondary shaft to drive feedback encoders, manual overrides, cooling fans, or secondary braking systems. This design simplifies drive-train layout, reduces footprint size, and minimizes dynamic balance discrepancies.

20+ Years of Manufacturing Integrity

Deep industry heritage since 2006, ensuring stable automated production lines and long-term supply security.

100% In-House Loading Tests

Every single motor is subjected to automated dynamic balancing, noise checks, and acoustic tests under real industrial loads before leaving our dock.

Agile Custom Prototyping

We don't shrink away from non-standard blueprints. We rapidly customize shafts, integrated encoders, and specialized gearheads to fit your device housing.

Global Compliance Built-In

Our state-of-the-art facility runs fully compliant with international ISO9001, CE, RoHS, and REACH safety standards.

Production Workflow

Each step in our production cycle utilizes automated assembly and testing lines to preserve absolute torque consistency across manufacturing runs.

Localized Engineering Applications of Dual Shaft Motors

The practical value of dual shaft motors lies in their versatility. In real-world environments, dual shaft configurations resolve unique engineering trade-offs:

Medical Exoskeletons (Rehabilitation)

Primary Shaft: Drives high-torque planetary reduction systems to assist knee or hip rotation.

Rear Shaft: Direct-couples to multi-turn absolute encoders, offering milliradian feedback on limb positions for safety limit monitoring.

High Resolution Feedback

Automated Solar Tracking Arrays

Primary Shaft: Rotates the heavy dual-axis solar panels via self-locking worm gearboxes to resist wind load.

Rear Shaft: Houses a manual hand-crank override mechanism for service calibration during emergency maintenance outages.

Self-Locking Integrity

Warehouse AGVs & Smart Conveyors

Primary Shaft: Connects to drive wheels or belt assemblies for forward propulsion.

Rear Shaft: Connects directly to electromagnetic friction brakes to enable instant halt parameters inside automated warehouses.

Fail-Safe Emergency Stop

Technical Roadmap & Future Outlook

The core technology of mini DC motors is shifting towards higher power densities and intelligent controls. Goaxis Pro’s R&D roadmap focuses on four key initiatives:

  • Transition to Brushless DC (BLDC) Dual Shafts: Developing brushless variants of our planetary and worm gear models to extend operating life beyond 10,000 hours, removing carbon brush friction limits while retaining dual shaft flexibility.
  • Integrated Magnetic Encoder (Hall Sensor) Architecture: Standardizing integrated magnetic ring configurations on the rear shaft. This will allow clients to receive plug-and-play position feedback without needing separate retrofits.
  • High-Efficiency Gear Topology: Implementing helical gear cutting techniques to reduce planetary gear noise below 42dB, keeping transmissions smooth for residential and medical appliances.
  • Additive Shaft Customization: Standardizing modular D-shafts, keyways, split pins, and threaded extensions to minimize CNC tooling setup time for custom requests.

China Factory Supply Chain Resilience & Cost-Efficiency

Technical Questions & Answers (FAQ)

Essential guidance on custom dual shaft specifications, planetary selections, and design customization.

What mechanical options exist for the secondary/rear shaft configuration?
The rear shaft extension can be fully customized with flat D-cuts, keyways, screw threads, cross-pinned holes, or smooth round outputs. It typically connects to optical or magnetic encoders, cooling fans, manual override handwheels, or secondary fail-safe electromagnetic brakes.
How do you guarantee concentricity between the front and rear shafts?
We use a single-pass grinding process on our CNC lathing centers to machine the entire rotor shaft from one piece of steel stock. This guarantees that both the front and rear extensions share a common center axis, keeping runout under 0.03mm.
What voltages are available for these custom motors?
We offer voltages spanning 5V, 6V, 12V, 24V, and 36V DC, as well as AC lines operating up to 220V/240V. This covers low-voltage medical exoskeletons, robotics joint control, and high-power industrial equipment.
Why are planetary gearboxes preferred over spur gearboxes in high-torque setups?
Planetary gearboxes share load forces across multiple planet gears, increasing torque capacity within a compact diameter. This makes them ideal for tight spaces like exoskeleton joints and robotic arms, where standard spur gears would wear out under heavy loads.
Can I request a worm gear configuration on a dual shaft motor?
Yes. We frequently build systems combining a 90-degree worm gear drive (such as our JGY-370 series) on the front shaft to prevent back-driving, while keeping the rear shaft free for an encoder or brake installation.
What is the typical prototype lead-time for a custom shaft shape?
We can generate CAD approval drawings within 48 hours. Once drawings are approved, we fabricate and ship working prototypes in 10 to 15 days, using our in-house CNC wire-cut machines and lathes.
Do you support magnetic encoder integration for closed-loop control?
Yes, we supply built-in magnetic Hall-effect encoders or optical disks. These mount directly onto the rear shaft, providing feedback on speed and rotational direction for closed-loop motion control systems.
What safety certifications are provided for European and US markets?
Our facilities and motors comply with CE, RoHS, and REACH requirements. When requested, we can use UL-certified insulation materials to simplify compliance checks for your finished assemblies.
How does your factory ensure the durability of high-torque gear motors?
We use high-grade steel gears and premium synthetic lubricants. Every production batch undergoes continuous life-cycle testing on our aging shelves, running under load for up to 1,000 hours to ensure they meet our reliability standards.
What is the Minimum Order Quantity (MOQ) for custom OEM configurations?
Standard OEM production runs start with an MOQ of 1,000 units. However, we support lower order quantities during early design phases, helping you validate prototypes and initial test runs before ramping up to mass production.
