상품 특징

• Specifications: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x33.2mm(1.66x1.66x1.31in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 226g.
• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.29Nm (41.07oz·in), Rated current 0.4A, Resistance 30Ω, Inductance 38mH±20%, Rotor inertia approx 41g.cm².
• Safety: With safe and reliable operation, this 42mm 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; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Important Notes: 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 3D printers, DIY robots, CNC machines, and other automated systems. Its compact size and high torque suit demanding applications.
• More Power, Less Noise: 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.
