상품 특징

• Specifications: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x22.5mm, (1.66x1.66x0.89in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 143g.
• Parameters: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.16Nm (22.66oz·in), Resistance 4.2Ω, Rated current 0.8A, Inductance 4.3mH±20%, Rotor inertia approx 23g.cm².
• Safety Compliance: This Nema17 Step Motor ensures safe and reliable performance, and here are its 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 temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Important Considerations: 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 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: 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.
