상품 특징

• Size Specifications: Nema 23 Stepper Motor dimensional parameters are as follows. Body size 57x57x81.4mm(2.25x2.25x3.21in), Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, Installation hole distance 47mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 1180g.
• Characteristics: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 2.2Nm (311.55oz·in), Rated current 4.0A, Resistance 0.6Ω, Inductance 1.8mH±20%, Rotor inertia approx 565g.cm².
• Safety Specifications: This Nema23 Stepper Motor ensures safe and reliable performance, and here are its key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
• More Power, Less Noise: 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 Points: 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). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the Nema 23 Stepper Motor offers compact size and high torque for tough tasks.
