상품 특징

• Dimensional details: The physical dimensions of a Nema 23 Stepper Motor are summarized below. Body size 57x57x75.4mm, (2.25x2.25x2.97in), Installation hole distance 47mm, Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 1082g.
• Characteristics: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 2Nm (283.22oz·in), Rated current 4.2A, Resistance 0.6Ω, Inductance 1.8mH±20%, Rotor inertia approx 495g.cm².
• Safety Specifications: The safe and reliable operation of this 57mm Stepper Motor is supported by these 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 temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• High Torque Low Noise: Leveraging reinforced steel cores and meticulously wound coils, this Nema 23 Step Motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
• Important Insights: Faster speeds lead to lower torque, so the recommended range is 0–600 RPM. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 24–36V DC). The Nema 23 Stepper Motor fits 3D printers, DIY robots, CNC machines, and other automated systems, offering a small size and high torque for performance-driven tasks.
