상품 특징

• Characteristics: Nema 17 linear actuator stepper motor with 150mm T8x8 lead screw, 2 Phase, Step angle 1.8‌dge(200 steps/rev), Holding torque 0.44Nm (62.31oz·in), Resistance 1.7Ω, Rated current 1.7A, Rotor inertia approx 60g.cm², Inductance 3.1mH±20%.
• Specifications: Dimensional parameters of Nema 17 lead screw stepper motor are as follows. Body size 42x42x39.2mm (1.66x1.66x1.55in), Lead screw TR8x8 150mm, Installation hole distance 31mm, Weight 340g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , incl. Cable 1M.
• Safety Data: This Nema 17 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; 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; Temperature rise 80K MAX.
• Smooth, Powerful Drive: This upgraded Nema 17 Stepper Motor with T8 Lead Screw utilizes fortified steel cores and optimized windings to reliably deliver up to 20% increased holding torque. Designed specifically for low-noise output, it fosters smoother machine functionality and reduces ambient sound interference effectively.
• Important Insights: Higher speed leads to a reduction in torque, with operation recommended at 0–600 RPM. Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 12–24V DC). The 42mm Stepper Motor with T8 Lead Screw fits 3D printers, DIY robots, CNC machines, and other automated systems, offering a small size and high torque for performance-driven tasks.
