상품 특징

• Specifications: 0.9deg Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x38.75mm, (1.66x1.66x1.53in), Installation hole distance 31mm, Shaft length φ5mm, Shaft diameter 22mm, D-cut length 15mm Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 294g.
• Performance Data: Nema 17 Stepper Motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 32Ncm (45.32oz·in), Resistance 2.5Ω, Rated current 1.3A, Inductance 5.0mH±20%, Rotor inertia approx 60g.cm².
• Safety Compliance: This Nema 17 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].
• Significant Torque Upgrade: Experience steadier operation with our enhanced Nema 17 Stepper Motors. 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 Points: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM for. Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (12–24V DC range). Widely used in 3D printers, DIY robots, CNC machines, and automation systems, the 42mm Stepper Motor offers compact size and high torque for tough tasks.
