상품 특징

• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.47Nm (66.56oz·in), Resistance 1.7Ω, Rated current 1.7A, Inductance 3.5mH±20%, Rotor inertia approx 60g.cm².
• Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x37.5mm(1.66x1.66x1.48in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, with Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 291g.
• Safety Data: The safe and reliable operation of this 42 Step Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Temperature rise 80K MAX.
• Smarter Core Design: 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.
• Notes to Remember: 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 ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
