Nema 17 Stepper Motor 1.8° 2 Phase High Torque 0.41Nm(58.06oz·in) Bipolar 42x40mm 1.5A 2.0Ω 4-Wire Shaft 24mm φ5mm 42 Stepper Motor Cable 1M for 3D Printer DIY Robot CNC Machine
Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x40mm, (1.66x1.66x1.58in), 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 295g.
Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.41Nm (58.06oz·in), Resistance 2.0Ω, Rated current 1.5A, Inductance 3.8mH±20%, Rotor inertia approx 60g.cm².
Safety Specifications: The safe and reliable operation of this 42 Stepper Motor is supported by these 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 temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
Key Information: Increasing speed lowers torque, with the recommended range of 0–600 RPM. Lower current results in lower torque and temperature rise, while reduced voltage decreases torque (range: 12–24V DC). 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: Engineered for minimal noise interference, our enhanced Nema 17 Step Motor boasts up to 20% greater holding torque through its higher-grade steel core construction and optimized winding technique. Experience smoother machine cycles with less surrounding disruption.
