상품 특징

• Dimensional details: The physical dimensions of a 0.9deg Nema 14 Round Stepper Motor are summarized below. Body size 35x35x14.95mm(1.38x1.38x0.59in), Shaft length φ5.0mm, Shaft diameter 15mm, D-cut length 15mm Installation hole distance 43.8mm, incl. Cable 0.5m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 64g.
• Specifications: Nema 14 mini stepper motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 3Ncm (4.25oz·in), Resistance 8.7Ω, Rated current 0.5A, Inductance 4.0mH±20%, Rotor inertia approx 8 g.cm².
• Safety: This Nema 14 Round Step 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].
• Advanced Steel Construction: Engineered for minimal noise interference, our enhanced Nema 14 Round Stepper Motors boasts up to 20% greater holding torque through its higher-grade steel core construction and optimized winding technique. Experience smoother machine cycles with less surrounding disruption.
• Key Points: Increased speed reduces torque, with operation suggested at 0–600 RPM. A lower current leads to lower torque and temperature rise, and reduced voltage results in lower torque (recommended range: 12–24V DC). Widely used in 3D printers, DIY robots, CNC machines, and automation systems, the 36mm Round Stepper Motor offers compact size and high torque for tough tasks.
