상품 특징

• Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x25.5mm(1.66x1.66x1.01in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, with Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 171g.
• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.26Nm (36.82oz·in), Resistance 1.5Ω, Rated current 2.0A, Inductance 1.8mH±20%, Rotor inertia approx 33g.cm².
• Safety: This 42mm Step Motor boasts safe and reliable operation, with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
• Smooth, Powerful Drive: Offering up to 20% more holding torque than typical Nema 17 Step Motor, our version focuses on low-noise operation. Its enhanced steel core and winding design ensure smooth motion and significantly decreased sound emission.
• Important Insights: As speed rises, torque falls, the recommended speed range is 0–600 RPM. Lower current reduces torque and temperature rise, and lower voltage results in less torque (12–24V DC range). The 42mm Stepper Motor fits 3D printers, DIY robots, CNC machines, and other automated systems, offering a small size and high torque for performance-driven tasks.
