Specifications: Dimensional parameters of 50.9:1 Geared nema 17 stepper motor with integrated planetary gearbox are as follows. Body size 42x42x91mm (1.66x1.66x3.59in), Shaft length 20mm, Shaft diameter Ø8mm, D-cut length 15mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), with Cable 1M, Weight 636g.
Safety Compliance: The safe and reliable operation of this Nema 17 Stepper Motor with planetary gear is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; 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; Temperature rise 80K MAX.
Significant Torque Upgrade: Leveraging reinforced steel cores and meticulously wound coils, this nema 17 planetary reducer stepper motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
Key Points to Remember: 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 42mm Stepper Motor with Planetary Gearbox is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
