Nema 17 Stepper Motor 2 Phase 1.8° 0.84Nm(118.95oz·in) High Torque Bipolar 60mm 2.3A 1.1Ω 4-Wire Shaft 24mm φ5mm 42 Stepper Motor Cable 1M for 3D Printer DIY Robot CNC Machine
Specifications: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x59.2mm, (1.66x1.66x2.34in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 473g.
Characteristics: Nema 17 Stepper Motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.84Nm (118.95oz·in), Rated current 2.3A, Resistance 1.1Ω, Inductance 2.8mH±20%, Rotor inertia approx 115g.cm².
Safety Compliance: This Nema 17 Stepper Motor boasts safe and reliable operation, with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Operation ambient temperature -20℃ ~+50℃ [-4°F~122°F]; Operation ambient humidity 15%RH~95%RH; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
Important Considerations: 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). The 42mm Stepper Motor is used in various applications like 3D printers, DIY robots, and CNC machines, offering a compact design and high torque for demanding tasks.
Advanced Steel Construction: 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.
