✓Safety Data: This Nema 11 Stepper Motor with planetary gear operates safely and reliably. Here are its key safety parameters: Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～123°F].
✓Important Notes: Increasing speed lowers torque, with the recommended range of 0–600 RPM. Lower current results in lower torque and temperature rise, while reduced voltage decreases torque (range: 12–24V DC). The 28mm Stepper Motor with Planetary Gearbox is used in 3D printers, DIY robots, CNC machines, and other automated systems. Its compact size and high torque suit demanding applications.
