상품 특징

• Specifications: Nema 23 Stepper Motor has the following various dimensional parameters. Body size 57x57x109.4mm(2.25x2.25x4.31in), Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, Installation hole distance 47mm, with Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 1664g.
• Parameters: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 3.5Nm (495.64oz·in), Resistance 1.0Ω, Rated current 4.2A, Inductance 4.0mH±20%, Rotor inertia approx 850g.cm².
• Safety: With safe and reliable operation, this 57 Stepper 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; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Smarter Core Design: 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 Considerations: 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 used in various applications like 3D printers, DIY robots, and CNC machines, offering a compact design and high torque for demanding tasks.
