상품 특징

• Size Specifications: 13.73:1 Geared Nema 11 Stepper Motor with Integrated Planetary Gearbox dimensional parameters are as follows. Body size 28x28x88mm (1.11x1.11x3.47in), Shaft length 18mm, Shaft diameter Ø6mm, D-cut length 13mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), incl. Cable 1M, Weight 325g.
• Performance Data: Ratio 13.73:1 Planetary Gearbox Nema 11 Stepper Motor, Step angle 1.8‌ Degree(200 steps/rev), 2 Phase Holding torque 11Ncm (15.58oz·in), Resistance 7.0Ω, Rated current 1.0A, Inductance 7.0mH±20%, Rotor inertia approx 29g.cm².
• Safety Specifications: This Nema 11 Stepper Motor with planetary gear ensures safe and reliable performance, and here are its key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Temperature rise 80K MAX; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• More Power, Less Noise: Built with advanced steel cores and precisely tuned windings, this nema 11 planetary reducer stepper motor generates up to 20% stronger holding torque while significantly reducing noise output. Achieve smoother machine motion and lower acoustic impact.
• Important Insights: Faster speeds reduce torque, with operation recommended at 0–600 RPM. Lower current reduces torque and temperature rise, and lower voltage also reduces torque (ideal voltage range: 12–24V DC). The 28mm Stepper Motor with Planetary Gearbox fits 3D printers, DIY robots, CNC machines, and other automated systems, offering a small size and high torque for performance-driven tasks.
