Specifications: 13.73:1 Geared nema 17 stepper motor with integrated planetary gearbox has the following various dimensional parameters. Body size 42x42x83mm (1.66x1.66x3.27in), Shaft length 20mm, Shaft diameter Ø8mm, D-cut length 15mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), incl. Cable 1M, Weight 583g.
Safety: This Nema 17 Stepper Motor with planetary gear boasts safe and reliable operation, with the following 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 temperature -20℃~+50℃ [-4°F~122°F]; Operation ambient humidity 15%RH~95%RH.
Precision-Built for Higher Output: 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.
Things to Note: 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). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor with Planetary Gearbox's compact size and high torque are perfect for a variety of demanding applications.
