상품 특징

• Size Specifications: Nema 23 Stepper Motor dimensional parameters are as follows. Body size 57x57x40.4mm(2.25x2.25x1.6in), Shaft length 21±0.5mm, Shaft diameter φ6.35mm, D-cut length 21mm, Installation hole distance 47mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 477g.
• Performance Data: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.72Nm (101.96oz·in), Resistance 1.6Ω, Rated current 2.0A, Rotor inertia approx 135g.cm², Inductance 3.5mH±20%.
• Safety Specifications: The safe and reliable operation of this 57mm Step Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• More Power, Less Noise: Leveraging reinforced steel cores and meticulously wound coils, this Nema 23 Step Motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
• Key Points: Faster speeds lead to lower torque, so the recommended range is 0–600 RPM. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 24–36V DC). 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.
