상품 특징

• Parameters: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Resistance 3.5Ω, Rated current 1.0A, Inductance 3.4mH±20%, Rotor inertia approx 16.5g.cm².
• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x20.5mm(1.66x1.66x0.81in), 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 121g.
• Safety Specifications: This Nema17 Step Motor ensures safe and reliable performance, and here are its 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.
• Key Details: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (12–24V DC range). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor is compact yet provides high torque for heavy-duty tasks.
• Exceptionally Quiet Powerhouse: Experience steadier operation with our enhanced Nema 17 Step Motor. Superior steel cores and optimized windings produce up to 20% higher holding torque. Engineered for quiet running, it reduces vibration and environmental sound interference.
