상품 특징

• Characteristics: Nema 17 linear actuator stepper motor with 400mm T8x8 lead screw, 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 0.44Nm (62.31oz·in), Resistance 1.7Ω, Rated current 1.7A, Rotor inertia approx 60g.cm², Inductance 3.1mH±20%.
• Dimensional details: The physical dimensions of a Nema 17 lead screw stepper motor are summarized below. Body size 42x42x39.2mm (1.66x1.66x1.55in), Lead screw TR8x8 400mm, Installation hole distance 31mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-) , incl. Cable 1M, Weight 414g.
• Safety: Operating safely and reliably, this Nema17 lead screw Step motor with flange nut comes with the following 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～122°F].
• Precision-Built for Higher Output: Generate up to 20% stronger holding torque compared to standard units with this Nema 17 Stepper Motor with T8 Lead Screw. Its robust steel core construction and specialized winding design minimize operational noise, enabling quieter and more efficient machinery.
• Key Points to Remember: As speed increases, torque decreases. The ideal speed range is 0–600 RPM. Lower current lowers both torque and temperature rise, and lower voltage reduces torque (12–24V DC recommended). The 42mm Stepper Motor with T8 Lead Screw is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
