Nema 17 Stepper Motor TR8x8 100mm with T8 Lead Screw 1.8° 2 Phase High Torque 0.55Nm (77.89oz·in) Bipolar 1.7A 2.0Ω 48mm 42 Step Motor 4-Wire Connector Cable 1M for 3D Printer DIY Robot CNC
Dimensional details: The physical dimensions of a Nema 17 lead screw stepper motor are summarized below. Body size 42x42x47.3mm (1.66x1.66x1.87in), Lead screw TR8x8 100mm , Installation hole distance 31mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-) , incl. Cable 1M, Weight 385g.
Characteristics: Nema 17 linear actuator stepper motor with 100mm T8x8 lead screw, 2 Phase, Step angle 1.8 Degree(200 steps/rev), Holding torque 0.55Nm (77.89oz·in), Resistance 2.0Ω, Rated current 1.7A, Rotor inertia approx 72g.cm², Inductance 4.7mH±20%.
Safety: Operating safely and reliably, this Nema17 lead screw Step motor with anti-backlash nut with 100mm T8x8 lead screwcomes with 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].
Important Insights: Increased speed reduces torque, with operation suggested at 0–600 RPM. A lower current leads to lower torque and temperature rise, and reduced voltage results in lower torque (recommended 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.
Smooth, Powerful Drive: 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.
