상품 특징

• Specifications: Dimensional parameters of 50.9:1 Geared nema 14 stepper motor with integrated planetary gearbox are as follows. Body size 35x35x80mm (1.38x1.38x3.15in), Shaft length 20mm, Shaft diameter Ø8mm, D-cut length 15mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), incl. Cable 1M, Weight 449g.
• Performance Data: Ratio 50.9:1 Planetary Gearbox 14 Stepper Motor, Step angle 1.8‌ Degree(200 steps/rev), 2 Phase Holding torque 26Ncm (36.82oz·in), Resistance 2.7Ω, Rated current 1.2A, Inductance 2.9mH±20%, Rotor inertia approx 180g.cm².
• Safety Data: This Nema 14 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 resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Temperature rise 80K MAX.
• Exceptionally Quiet Powerhouse: Built with advanced steel cores and precisely tuned windings, this nema 14 planetary reducer stepper motor generates up to 20% stronger holding torque while significantly reducing noise output. Achieve smoother machine motion and lower acoustic impact.
• Notes to Remember: 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 35mm Stepper Motor with Planetary Gearbox is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
