Special Features

  • Dimensional details: The physical dimensions of a 99.05:1 Geared nema 17 stepper motor with integrated planetary gearbox are summarized below. 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-), incl. Cable 1M, Weight 638g.
  • Specifications: Ratio 99.05:1 Planetary Gearbox 17 Stepper Motor, Step angle 1.8‌ Degree(200 steps/rev), 2 Phase Holding torque 0.55Nm (77.89oz·in), Resistance 2.0Ω, Rated current 1.7A, Inductance 4.0mH±20%, Rotor inertia approx 72g.cm².
  • Safety Specifications: This Nema 17 Stepper Motor with planetary gear ensures safe and reliable performance, and 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～122°F].
  • Unlock Machine Capability: 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.
  • Important Notes: Higher speed leads to a reduction in torque, with operation recommended at 0–600 RPM. Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 12–24V DC). The 42mm 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.
