Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.84Nm (118.95oz·in), Rated current 2.3A, Resistance 1.5Ω, Inductance 2.8mH±20%, Rotor inertia approx 115g.cm².
Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x59.2mm, (1.66x1.66x2.34in), 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 488g.
Operational Safety: This Nema17 Step 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.
Significant Torque Upgrade: This upgraded Nema 17 Step Motor utilizes fortified steel cores and optimized windings to reliably deliver up to 20% increased holding torque. Designed specifically for low-noise output, it fosters smoother machine functionality and reduces ambient sound interference effectively.
Key Points: Higher speed leads to a reduction in torque, with operation recommended at 0–600 RPM and closed-loop up to 1800 RPM. Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 12–24V DC). 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.
