상품 특징

• Dimensional details: The physical dimensions of a 3 Pack Nema 17 lead screw stepper motor are summarized below. Body size 42x42x38.7mm (1.66x1.66x1.53in), Lead screw TR8x8 350mm, Installation hole distance 31mm, Weight 401g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M.
• Parameters: Nema 17 linear actuator stepper motor with 350mm T8x8 lead screw, 2 Phase, Step angle 1.8‌dge(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 Specifications: The safe and reliable operation of this Nema 17 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: 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). 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: 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.
