상품 특징

• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.84Nm (118.95oz·in), Resistance 1.5Ω, Rated current 2.3A, Inductance 2.8mH±20%, Rotor inertia approx 115g.cm².
• Specifications: Dimensional parameters of Nema 17 Stepper Motor are as follows. Body size 42x42x59.2mm(1.66x1.66x2.34in), 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 488g.
• Safety Compliance: With safe and reliable operation, this 42 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.
• Unlock Machine Capability: 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 Details: 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 perfect for 3D printers, DIY robots, CNC machines, and other automated systems, offering a compact size and high torque for demanding tasks.
