상품 특징

• Dimensional details: The physical dimensions of a 3 Pack Nema 17 lead screw stepper motor are summarized below. Body size 42x42x39.2mm (1.66x1.66x1.55in), Lead screw TR8x8 310mm, Installation hole distance 31mm, Weight 391g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M.
• Parameters: Nema 17 linear actuator stepper motor with 310mm T8x8 lead screw, 2 Phase, Step angle 1.8‌dge(200 steps/rev), Holding torque 0.44Nm (62.31oz·in), Rated current 1.7A, Resistance 1.7Ω, Inductance 3.1mH±20%, Rotor inertia approx 60g.cm².
• Safety Specifications: The safe and reliable operation of this Nema17 lead screw linear Step motor with flange nut is supported by these 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].
• Notes 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 ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
• Smarter Core Design: 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.
