상품 특징

• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x27.5mm, (1.66x1.66x1.09in), 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 194g.
• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.28Nm (39.65oz·in), Resistance 1.6Ω, Rated current 1.6A, Inductance 1.7mH±20%, Rotor inertia approx 34g.cm².
• Operational Safety: With safe and reliable operation, this Nema 17 Stepper 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.
• Significant Torque Upgrade: 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 Points: 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). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Stepper Motor offers compact size and high torque for tough tasks.
