상품 특징

• Dimensional data: Key dimensions for 0.9deg Nema 14 Round Stepper Motor include the following. Body size 35x35x19.85mm, (1.38x1.38x0.79in), Installation hole distance 43.8mm, Shaft length φ5.0mm, Shaft diameter 15mm, D-cut length 15mm with Cable 0.5m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 92g.
• Characteristics: Nema 14 mini stepper motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 8Ncm (11.33oz·in), Resistance 17Ω, Rated current 0.4A, Rotor inertia approx 15 g.cm², Inductance 10.5mH±20%.
• Operational Safety: With safe and reliable operation, this Nema 14 Round Step Motor features 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.
• Exceptionally Quiet Powerhouse: 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.
• Important Details: 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). The 36mm Round Stepper Motor is perfect for 3D printers, DIY robots, CNC machines, and automation systems, offering a compact size and high torque for demanding tasks.
