Characteristics: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8 Degree (200 steps/rev), Holding torque 0.16Nm (22.66oz·in), Rated current 0.8A, Resistance 3.7Ω, Inductance 4.3mH±20%, Rotor inertia approx 23g.cm².
Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x22.5mm(1.66x1.66x0.89in), 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 141g.
Safety: This Nema17 Stepper Motor ensures safe and reliable performance, and here are its key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
Important Insights: 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). The 42mm Stepper Motor fits 3D printers, DIY robots, CNC machines, and other automated systems, offering a small size and high torque for performance-driven tasks.
Smooth, Powerful Drive: 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.
