상품 특징

• Parameters: Nema 17 linear actuator stepper motor with 400mm 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.
• Dimensional data: Key dimensions for 3 Pack Nema 17 lead screw stepper motor include the following. Body size 42x42x39.2mm (1.66x1.66x1.55in), Lead screw TR8x8 400mm, Installation hole distance 31mm, Weight 414g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M.
• Operational Safety: The safe and reliable operation of this Nema17 lead screw Step motor with flange nut is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Temperature rise 80K MAX; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• More Power, Less Noise: Experience steadier operation with our enhanced Nema 17 Stepper Motor with T8 Lead Screw. Superior steel cores and optimized windings produce up to 20% higher holding torque. Engineered for quiet running, it reduces vibration and environmental sound interference.
• Important Notes: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM. Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (12–24V DC range). The 42mm Stepper Motor with T8 Lead Screw is used in 3D printers, DIY robots, CNC machines, and other automated systems. Its compact size and high torque suit demanding applications.
