상품 특징

• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.41Nm (58.06oz·in), Rated current 1.5A, Resistance 2.0Ω, Inductance 3.8mH±20%, Rotor inertia approx 60g.cm².
• Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x40mm, (1.66x1.66x1.58in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 296g.
• Operational Safety: This 42mm 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 temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Precision-Built for Higher Output: 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.
• Key Points 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 widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
