상품 특징

• Specifications: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.6Nm (84.97oz·in), Resistance 1.6Ω, Rated current 2.3A, Rotor inertia approx 85g.cm², Inductance 2.0mH±20%.
• Performance Data: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x46.7mm(1.66x1.66x1.84in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 368g.
• Safety: The safe and reliable operation of this Nema 17 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 temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Temperature rise 80K MAX.
• More Power, Less Noise: This upgraded Nema 17 Step Motor utilizes fortified steel cores and optimized windings to reliably deliver up to 20% increased holding torque. Designed specifically for low-noise output, it fosters smoother machine functionality and reduces ambient sound interference effectively.
• Important Notes: Higher speed leads to a reduction in torque, with operation recommended at 0–600 RPM and closed-loop up to 1800 RPM. Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 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.
