상품 특징

• Dimensional data: Key dimensions for Nema 23 Stepper Motor include the following. Body size 57x57x109.4mm, (2.25x2.25x4.31in), 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 1664g.
• Characteristics: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 3.5Nm (495.64oz·in), Rated current 4.2A, Resistance 1.0Ω, Inductance 4.0mH±20%, Rotor inertia approx 850g.cm².
• Operational Safety: The safe and reliable operation of this 57 Step Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
• Elevate Your Equipment: Offering up to 20% more holding torque than typical Nema 23 Step Motor, our version focuses on low-noise operation. Its enhanced steel core and winding design ensure smooth motion and significantly decreased sound emission.
• Notes to Remember: As speed increases, torque decreases. Faster speeds lead to lower torque, so the recommended range is 0–600 RPM. Lower current lowers both torque and temperature rise, and lower voltage reduces torque (24–36V DC recommended). The Nema 23 Stepper Motor is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
