상품 특징

• Dimensional data: Key dimensions for Nema 23 Stepper Motor include the following. Body size 57x57x75.4mm(2.25x2.25x2.97in), 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 1082g.
• Parameters: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 2Nm (283.22oz·in), Resistance 0.6Ω, Rated current 4.2A, Inductance 1.8mH±20%, Rotor inertia approx 495g.cm².
• Safety Data: This Nema23 Step Motor ensures safe and reliable performance, and here are its 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
• Smooth, Powerful Drive: 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 to Remember: 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). The Nema 23 Stepper Motor is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
