상품 특징

• Specifications: Dimensional parameters of 19.19:1 Geared Nema 11 Stepper Motor with Integrated Planetary Gearbox 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-), Cable 1M, Weight 325g.
• Characteristics: Ratio 19.19:1 Planetary Gearbox Nema 11 Stepper Motor, 2 Phase, Step angle 1.8‌dge(200 steps/rev), Holding torque 11Ncm (15.58oz·in), Resistance 7.0Ω, Rated current 1.0A, Rotor inertia approx 29g.cm², Inductance 7.0mH±20%.
• Safety: With safe and reliable operation, this Nema 11 Stepper Motor with planetary gear features the following 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.
• Significant Torque Upgrade: 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.
• Key Points to Remember: 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 is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
