Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x59.2mm(1.66x1.66x2.34in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, with Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 473g.
Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8 Degree (200 steps/rev), Holding torque 0.84Nm (118.95oz·in), Resistance 1.1Ω, Rated current 2.3A, Inductance 2.8mH±20%, Rotor inertia approx 115g.cm².
Safety Specifications: Operating safely and reliably, this Nema17 Step motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Temperature rise 80K MAX; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
Key Details: 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). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor is compact yet provides high torque for heavy-duty tasks.
Exceptionally Quiet Powerhouse: 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.
