상품 특징

• Characteristics: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Rated current 1.0A, Resistance 3.5Ω, Inductance 3.4mH±20%, Rotor inertia approx 16.5g.cm².
• Specifications: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x20.5mm, (1.66x1.66x0.81in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 121g.
• Safety Compliance: The safe and reliable operation of this 42 Step Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
• Important Considerations: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (12–24V DC range). The 42mm Stepper Motor is used in various applications like 3D printers, DIY robots, and CNC machines, offering a compact design and high torque for demanding tasks.
• Advanced Steel Construction: Experience steadier operation with our enhanced Nema 17 Step Motor. Superior steel cores and optimized windings produce up to 20% higher holding torque. Engineered for quiet running, it reduces vibration and environmental sound interference.
