상품 특징

• Size Specifications: Nema 11 Stepper Motor dimensional parameters are as follows. Body size 28x28x50.4mm(1.11x1.11x1.99in), Shaft length 20±0.5mm, Shaft diameter φ5mm, D-cut length 15mm, Installation hole distance 23mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 203g.
• Characteristics: Nema 11 mini stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 15Ncm (21.24oz·in), Rated current 0.7A, Resistance 10.6Ω, Inductance 8.5mH±20%, Rotor inertia approx 19g.cm².
• Safety Specifications: This Nema11 Stepper Motor operates safely and reliably. Here are its 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 Details: 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). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 28mm Stepper Motor is compact yet provides high torque for heavy-duty tasks.
• Exceptionally Quiet Powerhouse: 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.
