상품 특징

• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 42Ncm (59.48oz·in), Rated current 1.3A, Resistance 2.5Ω, Inductance 6.7mH±20%, Rotor inertia approx 85g.cm².
• Size Specifications: 0.9deg Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x47.5mm, (1.66x1.66x1.88in), Installation hole distance 31mm, Shaft length φ5mm, Shaft diameter 22mm, D-cut length 15mm incl. Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 373g.
• Operational Safety: The safe and reliable operation of this Nema 17 Step Motor 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.
• High Torque Low Noise: Generate up to 20% stronger holding torque compared to standard units with this Nema 17 Stepper Motors. Its robust steel core construction and specialized winding design minimize operational noise, enabling quieter and more efficient machinery.
• Things to Note: As speed increases, torque decreases. The ideal speed range is 0–600 RPM. Lower current lowers both torque and temperature rise, and lower voltage reduces torque (12–24V DC recommended). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
