상품 특징

• Specifications: Nema 17 Stepper Motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 16Ncm (22.66oz·in), Resistance 1.7Ω, Rated current 1.2A, Inductance 3.0mH±20%, Rotor inertia approx 41g.cm².
• Dimensional data: Key dimensions for 0.9deg Nema 17 Stepper Motor include the following. Body size 42x42x33.3mm, (1.66x1.66x1.32in), Installation hole distance 31mm, Shaft length φ5mm, Shaft diameter 17mm, D-cut length 13mm Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 235g.
• Operational Safety: This Nema 17 Stepper Motor boasts safe and reliable operation, 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
• Advanced Steel Construction: 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 Considerations: 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 is used in various applications like 3D printers, DIY robots, and CNC machines, offering a compact design and high torque for demanding tasks.
