Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x20.5mm, (1.66x1.66x0.81in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 124g.
Characteristics: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Rated current 1.0A, Resistance 4.2Ω, Inductance 3.4mH±20%, Rotor inertia approx 16.5g.cm².
Operational Safety: Operating safely and reliably, this Nema 17 Step motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
Key Points: 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). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor offers compact size and high torque for tough tasks.
Significant Torque Upgrade: 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.
