상품 특징

• Size Specifications: Nema 8 Stepper Motor dimensional parameters are as follows. Body size 20x20x27mm, (0.79x0.79x1.07in), Installation hole distance 15.5mm, Shaft length 10±0.5mm, Shaft diameter φ4mm, D-cut length 7mm, incl. Cable 0.5m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 47g.
• Parameters: Nema 8 mini Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 1.6Ncm (2.27oz·in), Resistance 13Ω, Rated current 0.4A, Inductance 3.3mH±20%, Rotor inertia approx 2.0g.cm².
• Operational Safety: This Nema8 Stepper 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].
• Key Points: Faster speeds lead to lower torque; the recommended operating range is 0–600 RPM. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 12–24V DC). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 20mm Stepper Motor offers compact size and high torque for tough tasks.
• Significant Torque Upgrade: Our upgraded Nema 8 Step Motor delivers up to 20% greater holding torque than typical models. Featuring enhanced steel cores and refined windings, it operates with noticeably reduced noise for smoother, less disruptive machine performance.
