상품 특징

• Dimensional details: The physical dimensions of a Nema 11 Stepper Motor are summarized below. Body size 28x28x22.4mm, (1.11x1.11x0.89in), Installation hole distance 23mm, Shaft length 20±0.5mm, Shaft diameter φ5mm, D-cut length 15mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 76g.
• Characteristics: Nema 11 micro stepper motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 3Ncm (4.25oz·in), Rated current 0.4A, Resistance 19Ω, Inductance 5.1mH±20%, Rotor inertia approx 5g.cm².
• Safety Specifications: The safe and reliable operation of this Nema 11 pancake stepper motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Key Information: 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). Used in 3D printers, DIY robots, CNC machines, and other systems, the 28mm Stepper Motor's compact size and high torque make it suitable for tough applications.
• Elevate Your Equipment: Our upgraded Nema 11 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.
