상품 특징

• Specifications: Dimensional parameters of Nema 17 Stepper Motor are as follows. Body size 42x42x27.5mm, (1.66x1.66x1.09in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 190g.
• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.28Nm (39.65oz·in), Rated current 1.6A, Resistance 1.2Ω, Inductance 1.7mH±20%, Rotor inertia approx 34g.cm².
• Safety Data: Operating safely and reliably, this Nema 17 Stepper motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
• Things to Note: 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). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
• High Torque Low Noise: 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.
