Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x22.5mm, (1.66x1.66x0.89in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, incl. Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 143g.
Specifications: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.16Nm (22.66oz·in), Resistance 4.2Ω, Rated current 0.8A, Rotor inertia approx 23g.cm², Inductance 4.3mH±20%.
Safety Specifications: 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 15%RH～95%RH; Temperature rise 80K MAX.
Key Information: As speed rises, torque falls, the recommended speed range is 0–600 RPM. Lower current reduces torque and temperature rise, and lower voltage results in less 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.
Elevate Your Equipment: Offering up to 20% more holding torque than typical Nema 17 Step Motor, our version focuses on low-noise operation. Its enhanced steel core and winding design ensure smooth motion and significantly decreased sound emission.
