상품 특징

• Specifications: 3 Pack Nema 17 lead screw stepper motor has the following various dimensional parameters. Body size 42x42x38.7mm (1.66x1.66x1.53in), Lead screw TR8x8 310mm, Installation hole distance 31mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M, Weight 388g.
• Parameters: Nema 17 linear actuator stepper motor with 310mm T8x8 lead screw, 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 0.44Nm (62.31oz·in), Rated current 1.7A, Resistance 2.2Ω, Inductance 3.1mH±20%, Rotor inertia approx 65g.cm².
• Safety: This Nema17 lead screw Step motor with flange nut operates safely and reliably. Here are its key safety parameters: Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Key Points: With higher speeds, torque decreases. The ideal range for operation is 0–600 RPM. Lower current results in reduced torque and temperature rise, while lower voltage reduces torque (recommended: 12–24V DC). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor with T8 Lead Screw offers compact size and high torque for tough tasks.
• Significant Torque Upgrade: Built with advanced steel cores and precisely tuned windings, this Nema 17 Stepper Motor with T8 Lead Screw generates up to 20% stronger holding torque while significantly reducing noise output. Achieve smoother machine motion and lower acoustic impact.
