상품 특징

• Size Specifications: 0.9deg Nema 17 Stepper Motor dimensional parameters are as follows. Body size 35x35x46.8mm(1.38x1.38x1.85in), Shaft length φ5mm, Shaft diameter 22mm, D-cut length 15mm Installation hole distance 31mm, with Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 375g.
• Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 42Ncm (59.48oz·in), Resistance 3.0Ω, Rated current 1.3A, Rotor inertia approx 85g.cm², Inductance 6.7mH±20%.
• Safety Specifications: Operating safely and reliably, this Nema17 Stepper motor comes with 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.
• Unlock Machine Capability: 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.
• Important Details: 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). The 42mm Stepper Motor is perfect for 3D printers, DIY robots, CNC machines, and automation systems, offering a compact size and high torque for demanding tasks.
