상품 특징

• Size Specifications: Nema 23 Stepper Motor dimensional parameters are as follows. Body size 57x57x109.4mm, (2.25x2.25x4.31in), Installation hole distance 47mm, Shaft length 21±0.5mm, Shaft diameter φ10mm, D-cut length 21mm, incl. Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 1663g.
• Performance Data: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 3.5Nm (495.64oz·in), Resistance 1.0Ω, Rated current 4.2A, Rotor inertia approx 850g.cm², Inductance 4.0mH±20%.
• Operational Safety: This Nema23 Step Motor operates safely and reliably. Here are its key safety parameters: Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature 15%RH～95%RH-20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Advanced Steel Construction: 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.
• Key Details: 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). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the Nema 23 Stepper Motor is compact yet provides high torque for heavy-duty tasks.
