상품 특징

• Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x22.5mm(1.66x1.66x0.89in), 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 143g.
• Characteristics: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.16Nm (22.66oz·in), Rated current 0.8A, Resistance 4.2Ω, Inductance 4.3mH±20%, Rotor inertia approx 23g.cm².
• Safety Data: The safe and reliable operation of this 42mm Stepper Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
• Notes to Remember: As speed rises, torque falls, the recommended speed range is 0–600 RPM. Lower current reduces torque and temperature rise, and lower voltage results in less torque (12–24V DC range). The 42mm Stepper Motor is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
• Smarter Core Design: Offering up to 20% more holding torque than typical Nema 17 Step Motor, our version focuses on low-noise operation. Its enhanced steel core and winding design ensure smooth motion and significantly decreased sound emission.
