상품 특징

• Parameters: Nema17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.41Nm (58.06oz·in), Resistance 2.0Ω, Rated current 1.5A, Inductance 3.8mH±20%, Rotor inertia approx 60g.cm².
• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x40mm(1.66x1.66x1.58in), 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 295g.
• Safety Specifications: This 42mm Step Motor boasts safe and reliable operation, 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
• ​Exceptionally Quiet Powerhouse: Engineered for minimal noise interference, our enhanced Nema 17 Step Motor boasts up to 20% greater holding torque through its higher-grade steel core construction and optimized winding technique. Experience smoother machine cycles with less surrounding disruption.
• Key Details: Increasing speed lowers torque, with the recommended range of 0–600 RPM. Lower current results in lower torque and temperature rise, while reduced voltage decreases torque (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.
