상품 특징

• Parameters: Nema 17 linear actuator stepper motor with 210mm T8x8 lead screw, 2 Phase, Step angle 1.8‌ Degree(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 210mm, Installation hole distance 31mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M, Weight 359g.
• Safety Compliance: This Nema17 lead screw linear Step motor with flange nut operates safely and reliably. Here are its 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.
• Advanced Steel Construction: 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 Considerations: 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 used in various applications like 3D printers, DIY robots, and CNC machines, offering a compact design and high torque for demanding tasks.
