상품 특징

• Dimensional details: The physical dimensions of a Nema 17 Stepper Motor are summarized below. Body size 42x42x47.2mm, (1.66x1.66x1.86in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 356g.
• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.6Nm (84.97oz·in), Resistance 1.2Ω, Rated current 2.3A, Inductance 2.0mH±20%, Rotor inertia approx 85g.cm².
• Safety Specifications: With safe and reliable operation, this Nema 17 Step Motor features the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Temperature rise 80K MAX.
• Key Information: 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). Used in 3D printers, DIY robots, CNC machines, and other systems, the 42mm Stepper Motor's compact size and high torque make it suitable for tough applications.
• Elevate Your Equipment: 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.
