Specifications: Dimensional parameters of Nema 17 Stepper Motor are as follows. Body size 42x42x59.2mm, (1.66x1.66x2.34in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, incl. Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 473g.
Performance Data: Nema 17 Stepper Motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.84Nm (118.95oz·in), Resistance 1.1Ω, Rated current 2.3A, Rotor inertia approx 115g.cm², Inductance 2.8mH±20%.
Safety Data: The safe and reliable operation of this Nema 17 Step Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature 15%RH～95%RH-20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
Things to Note: Increased speed reduces torque, with operation suggested at 0–600 RPM. A lower current leads to lower torque and temperature rise, and reduced voltage results in lower torque (recommended range: 12–24V DC). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
High Torque Low Noise: Leveraging reinforced steel cores and meticulously wound coils, this Nema 17 Step Motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
