Specifications: 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, Rotor inertia approx 16.5g.cm², Inductance 3.4mH±20%.
Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x20.5mm(1.66x1.66x0.81in), 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 121g.
Safety Data: Operating safely and reliably, this Nema 17 Stepper motor comes with the following 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 ; Temperature rise 80K MAX.
Notes to Remember: 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 is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
Smarter Core Design: 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.
