상품 특징

• Dimensional details: The physical dimensions of a Nema 14 Stepper Motor are summarized below. Body size 35x35x28.2mm(1.38x1.38x1.12in), Shaft length 20.5±0.5mm, Shaft diameter φ5mm, D-cut length 16.5mm, Installation hole distance 26mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 157g.
• Specifications: Nema 14 mini stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 12Ncm (16.99oz·in), Resistance 4.5Ω, Rated current 0.6A, Rotor inertia approx 12g.cm², Inductance 6.5mH±20%.
• Safety: Operating safely and reliably, this Nema14 Stepper motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Important Insights: 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 35mm Stepper Motor fits 3D printers, DIY robots, CNC machines, and other automated systems, offering a small size and high torque for performance-driven tasks.
• Smooth, Powerful Drive: Our upgraded Nema 14 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.
