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.
