상품 특징

• Dimensional details: The physical dimensions of a 50.9:1 Geared Nema 11 Stepper Motor with Integrated Planetary Gearbox are summarized below. Body size 28x28x94mm (1.11x1.11x3.71in), Shaft length 18mm, Shaft diameter Ø6mm, D-cut length 13mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), with Cable 1M, Weight 349g.
• Parameters: Ratio 50.9:1 Planetary Gearbox Nema 11 Stepper Motor, 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 11Ncm (15.58oz·in), Rated current 1.0A, Resistance 7.0Ω, Inductance 7.0mH±20%, Rotor inertia approx 29g.cm².
• Safety Data: This Nema 11 Stepper Motor with planetary gear operates safely and reliably. Here are its key safety parameters: Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～122°F].
• Unlock Machine Capability: 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 Notes: Increasing speed lowers torque, with the recommended range of 0–600 RPM. Lower current results in lower torque and temperature rise, while reduced voltage decreases torque (range: 12–24V DC). The 28mm Stepper Motor with Planetary Gearbox is used in 3D printers, DIY robots, CNC machines, and other automated systems. Its compact size and high torque suit demanding applications.
