상품 특징

• Size Specifications: 19.19:1 Geared nema 17 stepper motor with integrated planetary gearbox dimensional parameters are as follows. Body size 42x42x83mm (1.66x1.66x3.27in), Shaft length 20mm, Shaft diameter Ø8mm, D-cut length 15mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), Cable 1M, Weight 586g.
• Characteristics: Ratio 19.19:1 Planetary Gearbox 17 Stepper Motor, 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 0.55Nm (77.89oz·in), Resistance 2.0Ω, Rated current 1.7A, Rotor inertia approx 72g.cm², Inductance 4.0mH±20%.
• Safety Data: Operating safely and reliably, this Nema 17 Stepper Motor with planetary gear comes with the following 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: Leveraging reinforced steel cores and meticulously wound coils, this nema 17 planetary reducer stepper motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
• Important Insights: 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 42mm 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.
