상품 특징

• Specifications: Dimensional parameters of 0.9deg Nema 17 Stepper Motor are as follows. Body size 42x42x20.4mm(1.66x1.66x0.81in), Shaft length φ5mm, Shaft diameter 17mm, D-cut length 13mm Installation hole distance 31mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 121g.
• Performance Data: Nema 17 pancake stepper motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 9Ncm (12.75oz·in), Resistance 9.1Ω, Rated current 0.4A, Inductance 12.5mH±20%, Rotor inertia approx 16.5g.cm².
• Safety Compliance: This Nema17 Stepper Motor 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
• Smooth, Powerful Drive: Generate up to 20% stronger holding torque compared to standard units with this Nema 17 Stepper Motors. Its robust steel core construction and specialized winding design minimize operational noise, enabling quieter and more efficient machinery.
• Important Insights: As speed increases, torque decreases. The ideal speed range is 0–600 RPM. Lower current lowers both torque and temperature rise, and lower voltage reduces torque (12–24V DC recommended). The 42mm Stepper Motor fits 3D printers, DIY robots, CNC machines, and automation systems, offering a small size and high torque for performance-driven tasks.
