상품 특징

• Size Specifications: Nema 17 lead screw stepper motor dimensional parameters are as follows. Body size 42x42x38.7mm (1.66x1.66x1.53in), Lead screw TR8x8 300mm, Installation hole distance 31mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-) , incl. Cable 1M, Weight 386g.
• Characteristics: Nema 17 linear actuator stepper motor with 300mm T8x8 lead screw, 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 0.44Nm (62.31oz·in), Resistance 2.2Ω, Rated current 1.7A, Rotor inertia approx 65g.cm², Inductance 3.1mH±20%.
• Safety Specifications: Operating safely and reliably, this Nema17 lead screw linear Step motor with flange nut comes with the following 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.
• Things to Note: Higher speeds lead to a decrease in torque, with operation recommended at 0–600 RPM. Reducing current lowers both torque and temperature rise, while lower voltage reduces torque (12–24V DC range). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor with T8 Lead Screw's compact size and high torque are perfect for a variety of demanding applications.
• High Torque Low Noise: Choose our upgraded Nema 17 Stepper Motor with T8 Lead Screw for increased holding torque and remarkably quiet function. Re-engineered steel cores and precision windings minimize noise, contributing to smoother overall system operation with less ambient disruption.
