Supplier's note

1. Technical Breakthroughs:

   • Hybrid Stepper Motor: Achieves 1.8° step angle precision for flawless motion control.
   • Planetary Gear Design: Delivers 20Nm torque in a compact package, 20% smaller than traditional gearboxes.
   • Integrated Cooling: Heat sinks reduce thermal resistance by 30%, enabling continuous operation.

2. Optimal Version Selection:

   • Base Model: Ideal for standard automation tasks (e.g., 3D printers) where fixed torque and moderate speed suffice.
   • Advanced Model: Suitable for industrial robotics or conveyor systems needing adjustable torque (up to 25Nm) and wider temperature tolerance.
   • Pro Model: Designed for heavy machinery or precision robotics requiring extreme torque (30Nm) and customizable gear ratios (up to 1:100). Its expanded temperature range ensures reliability in harsh environments.

With the Pro version’s 1:100 gear ratio, you can achieve torque up to 2,000Nm—tripling industry benchmarks—while maintaining low-speed stability. Pair this with its corrosion-resistant housing to ensure longevity in chemical processing plants.
