Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x40mm(1.66x1.66x1.58in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 295g.
Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8 Degree (200 steps/rev), Holding torque 0.41Nm (58.06oz·in), Resistance 2.0Ω, Rated current 1.5A, Rotor inertia approx 60g.cm², Inductance 3.8mH±20%.
Safety Data: With safe and reliable operation, this Nema 17 Stepper Motor features 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 15%RH～95%RH-20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
Notes to Remember: 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). The 42mm Stepper Motor is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
Smarter Core Design: 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.
