상품 특징

• Dimensional details: The physical dimensions of a Nema 17 lead screw stepper motor are summarized below. Body size 42x42x38.7mm (1.66x1.66x1.53in), Lead screw TR8x8 240mm, Installation hole distance 31mm, Weight 365g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , incl. Cable 1M.
• Characteristics: Nema 17 linear actuator stepper motor with 240mm T8x8 lead screw, 2 Phase, Step angle 1.8‌dge(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: With safe and reliable operation, this Nema 17 lead screw Step motor with flange nut features the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～122°F].
• Notes to Remember: 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). The 42mm Stepper Motor with T8 Lead Screw is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
• Smart Core Design: 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.
