상품 특징

• Dimensional data: Key dimensions for Nema 11 Stepper Motor include the following. Body size 28x28x30.8mm(1.11x1.11x1.22in), Shaft length 20±0.5mm, Shaft diameter φ5mm, D-cut length 15mm, Installation hole distance 23mm, with Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 115g.
• Parameters: Nema 11 pancake stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 8Ncm (11.33oz·in), Resistance 6.1Ω, Rated current 0.8A, Inductance 4.2mH±20%, Rotor inertia approx 8.5g.cm².
• Safety Data: This Nema 11 mini Stepper 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
• Notes to Remember: 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). The 28mm Stepper Motor is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
• Smarter Core Design: 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.
