상품 특징

• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (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.
• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x25.5mm, (1.66x1.66x1.01in), 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 171g.
• Operational Safety: The safe and reliable operation of this 42mm Stepper Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Key Points: 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). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor offers compact size and high torque for tough tasks.
• Significant Torque Upgrade: 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.
