상품 특징

• 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.
