Special Features

  • Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x33.2mm, (1.66x1.66x1.31in), 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 226g.
  • Specifications: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), 0.29Nm (41.07oz·in) Holding torque , Resistance 30Ω, Rated current 0.4A, Rotor inertia approx 41g.cm², Inductance 38mH±20%.
  • 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; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature 15%RH～95%RH-20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
  • Key Points to Remember: Higher speeds lead to a decrease in torque, with operation recommended at 0–600 RPM. Reducing current lowers both torque and temperature rise, while lower voltage reduces torque (12–24V DC range). The 42mm Stepper Motor is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
  • Precision-Built for Higher Output: Choose our upgraded Nema 17 Step Motor for increased holding torque and remarkably quiet function. Re-engineered steel cores and precision windings minimize noise, contributing to smoother overall system operation with less ambient disruption.
