상품 특징

• Specifications: Dimensional parameters of Nema 17 Stepper Motor are as follows. Body size 42x42x32.7mm, (1.66x1.66x1.29in), 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 226g.
• Parameters: Nema 17 Stepper Motors 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.29Nm (41.07oz·in), Resistance 30Ω, Rated current 0.4A, Inductance 38mH±20%, Rotor inertia approx 41g.cm².
• Safety Data: The safe and reliable operation of this Nema 17 Step Motor is supported by these 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].
• Things to Note: 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). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
• High Torque Low Noise: 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.
