상품 특징

• Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x25.5mm, (1.66x1.66x1.01in), 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 171g.
• Specifications: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.26Nm (36.82oz·in), Resistance 1.1Ω, Rated current 2.0A, Rotor inertia approx 33g.cm², Inductance 1.8mH±20%.
• Safety Specifications: This Nema17 Step Motor operates safely and reliably. 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 -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Key Information: 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). 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: 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.
