상품 특징

• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x37.5mm, (1.66x1.66x1.48in), 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 292g.
• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.47Nm (66.56oz·in), Resistance 2.1Ω, Rated current 1.7A, Rotor inertia approx 62g.cm², Inductance 3.5mH±20%.
• Operational Safety: This Nema 17 Stepper Motor boasts safe and reliable operation, with 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 -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Temperature rise 80K MAX.
• Key Points: 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). 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: 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.
