상품 특징

• Specifications: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.47Nm (66.56oz·in), Resistance 1.7Ω, Rated current 1.7A, Rotor inertia approx 60g.cm², Inductance 3.5mH±20%.
• Performance Data: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x37.5mm, (1.66x1.66x1.48in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, incl. Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 291g.
• Safety Compliance: With safe and reliable operation, this Nema 17 Stepper Motor features the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Temperature rise 80K MAX.
• Advanced Steel Construction: Built with advanced steel cores and precisely tuned windings, this Nema 17 Step Motor generates up to 20% stronger holding torque while significantly reducing noise output. Achieve smoother machine motion and lower acoustic impact.
• Important Considerations: With higher speeds, torque decreases. The ideal range for operation is 0–600 RPM, and up to 1800 RPM for closed-loop systems. Lower current results in reduced torque and temperature rise, while lower voltage reduces torque (recommended: 12–24V DC). 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.
