Size Specifications: Nema 23 Stepper Motor dimensional parameters are as follows. Body size 57x57x54.4mm, (2.25x2.25x2.15in), Installation hole distance 47mm, Shaft length 21±0.5mm, Shaft diameter φ8mm, D-cut length 21mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 724g.
Parameters: Nema 23 Stepper Motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 1.3Nm (184.1oz·in), Resistance 0.5Ω, Rated current 4.2A, Inductance 1.2mH±20%, Rotor inertia approx 300g.cm².
Operational Safety: This 57 mm 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.
Advanced Steel Construction: 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 Details: 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). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the Nema 23 Stepper Motor is compact yet provides high torque for heavy-duty tasks.
