상품 특징

• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x32.7mm(1.66x1.66x1.29in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 226g.
• Performance Data: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.29Nm (41.07oz·in), Rated current 0.4A, Resistance 30Ω, Inductance 38mH±20%, Rotor inertia approx 41g.cm².
• Safety Specifications: Operating safely and reliably, this Nema 17 Stepper 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.
• Exceptionally Quiet Powerhouse: Our upgraded Nema 17 Step Motor provides up to 20% higher holding torque. The refined steel core and advanced winding configuration promote efficient, smooth-running mechanics with substantially reduced operational noise for a cleaner working environment.
• Key Details: Faster speeds reduce torque, with operation recommended at 0–600 RPM and closed-loop up to 1800 RPM. Lower current reduces torque and temperature rise, and lower voltage also reduces torque (ideal voltage 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.
