• Safety Compliance: This Nema 11 Stepper Motor with planetary gear boasts safe and reliable operation, with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Temperature rise 80K MAX; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～96%RH.
• Key Points: 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). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 28mm Stepper Motor with Planetary Gearbox offers compact size and high torque for tough tasks.
