Dimensional data: Key dimensions for 5.18:1 Geared nema 17 stepper motor with integrated planetary gearbox include the following. Body size 42x42x76.6mm (1.66x1.66x3.02in), Shaft length 20mm, Shaft diameter Ø8mm, D-cut length 15mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), with Cable 1M, Weight 541g.
Safety Specifications: This Nema 17 Stepper Motor with planetary gear operates safely and reliably. Here are its 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～95%RH.
Smooth, Powerful Drive: Built with advanced steel cores and precisely tuned windings, this nema 17 planetary reducer stepper motor generates up to 20% stronger holding torque while significantly reducing noise output. Achieve smoother machine motion and lower acoustic impact.
Key Details: 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). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor with Planetary Gearbox is compact yet provides high torque for heavy-duty tasks.
