상품 특징

• Specifications: Dimensional parameters of Nema 23 Stepper Motor are as follows. Body size 57x57x100.4mm, (2.25x2.25x3.96in), Installation hole distance 47mm, Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 1499g.
• Parameters: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 3Nm (424.84oz·in), Resistance 0.8Ω, Rated current 4.2A, Inductance 2.8mH±20%, Rotor inertia approx 750g.cm².
• Safety Data: This Nema 23 Stepper Motor boasts safe and reliable operation, with 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Temperature rise 80K MAX.
• Significant Torque Upgrade: 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.
• Important 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). The Nema 23 Stepper Motor is perfect for 3D printers, DIY robots, CNC machines, and other automated systems, offering a compact size and high torque for demanding tasks.
