Parameters: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8dge (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.
Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x20.5mm, (1.66x1.66x0.81in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 121g.
Safety Specifications: This 42 Step Motor boasts safe and reliable operation, with 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 humidity 15%RH~95%RH; Operation ambient temperature -20℃ ~+50℃ [-4°F~122°F].
Key Information: 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). Used in 3D printers, DIY robots, CNC machines, and other systems, the 42mm Stepper Motor's compact size and high torque make it suitable for tough applications.
