상품 특징

• Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x25.5mm(1.66x1.66x1.01in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 171g.
• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.26Nm (36.82oz·in), Rated current 2.0A, Resistance 1.1Ω, Inductance 1.8mH±20%, Rotor inertia approx 33g.cm².
• Safety Data: This 42mm Step Motor boasts safe and reliable operation, with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
• Notes 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 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: 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.
