상품 특징

• Specifications: Dimensional parameters of Nema 23 Stepper Motor are as follows. Body size 57x57x54.4mm(2.25x2.25x2.15in), Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, Installation hole distance 47mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 724g.
• Performance Data: Nema 23 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 1.3Nm (184.1oz·in), Resistance 0.5Ω, Rated current 4.2A, Rotor inertia approx 300g.cm², Inductance 1.2mH±20%.
• Safety Compliance: Operating safely and reliably, this Nema 23 Stepper motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature 15%RH～95%RH-20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Exceptionally Quiet Powerhouse: 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.
• Things to Note: 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). 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.
