상품 특징

• Parameters: 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), Rated current 1.7A, Resistance 2.2Ω, Inductance 3.1mH±20%, Rotor inertia approx 65g.cm².
• Specifications: 3 Pack Nema 17 lead screw stepper motor has the following various dimensional parameters. Body size 42x42x38.7mm (1.66x1.66x1.53in), Lead screw TR8x8 150mm, Installation hole distance 31mm, Weight 341g, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-) , Cable 1M.
• Safety Compliance: The safe and reliable operation of this Nema 17 lead screw Step motor with flange nut is supported by these 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 temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Exceptionally Quiet Powerhouse: Experience steadier operation with our enhanced Nema 17 Stepper Motor with T8 Lead Screw. Superior steel cores and optimized windings produce up to 20% higher holding torque. Engineered for quiet running, it reduces vibration and environmental sound interference.
• Key Details: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM. Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (12–24V DC range). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor with T8 Lead Screw is compact yet provides high torque for heavy-duty tasks.
