상품 특징

• Dimensional details: The physical dimensions of a 0.9deg Nema 17 Stepper Motor are summarized below. Body size 42x42x25.65mm, (1.66x1.66x1.01in), Installation hole distance 31mm, Shaft length φ5mm, Shaft diameter 17mm, D-cut length 13mm with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 178g.
• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 17Ncm (24.07oz·in), Resistance 3.6Ω, Rated current 1.0A, Rotor inertia approx 33g.cm², Inductance 4.9mH±20%.
• Safety Specifications: With safe and reliable operation, this Nema 17 Stepper Motor features the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Precision-Built for Higher Output: 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.
• Key Points to Remember: 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). The 42mm Stepper Motor is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
