상품 특징

• Specifications: Dimensional parameters of Nema 14 Stepper Motor are as follows. Body size 35x35x20.5mm, (1.38x1.38x0.81in), Installation hole distance 26mm, Shaft length 20.5±0.5mm, Shaft diameter φ5mm, D-cut length 16.5mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 100g.
• Parameters: Nema 14 pancake stepper motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 7Ncm (9.91oz·in), Resistance 3.7Ω, Rated current 0.6A, Inductance 2.6mH±20%, Rotor inertia approx 7g.cm².
• Safety Data: This Nema 14 mini 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].
• Things to Note: 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). In 3D printers, DIY robots, and CNC machines, the 35mm Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
• High Torque Low Noise: 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.
