상품 특징

• Specifications: Dimensional parameters of Nema 23 Stepper Motor are as follows. Body size 57x57x109.4mm(2.25x2.25x4.31in), Shaft length 21±0.5mm, Shaft diameter φ10mm, D-cut length 21mm, Installation hole distance 47mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 1663g.
• Characteristics: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (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.
• Safety Compliance: This 57mm 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; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• ​Exceptionally Quiet Powerhouse: 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.
• Things to Note: 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). In 3D printers, DIY robots, and CNC machines, the Nema 23 Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
