상품 특징

• Parameters: Nema 17 linear actuator stepper motor with 200mm 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.
• Size Specifications: 3 Pack Nema 17 lead screw stepper motor dimensional parameters are as follows. Body size 42x42x39.2mm (1.66x1.66x1.55in), Lead screw TR8x8 200mm, Installation hole distance 31mm, Weight 355g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M.
• Safety Compliance: The safe and reliable operation of this Nema 17 lead screw Step motor with flange nut is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Temperature rise 80K MAX; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Unlock Machine Capability: Our upgraded Nema 17 Stepper Motor with T8 Lead Screw delivers up to 20% greater holding torque than typical models. Featuring enhanced steel cores and refined windings, it operates with noticeably reduced noise for smoother, less disruptive machine performance.
• Important Details: Faster speeds lead to lower torque; the recommended operating range is 0–600 RPM. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 12–24V DC). The 42mm Stepper Motor with T8 Lead Screw is perfect for 3D printers, DIY robots, CNC machines, and other automated systems, offering a compact size and high torque for demanding tasks.
