상품 특징

• Size Specifications: Nema 17 Stepper Motor dimensional parameters are as follows. Body size 42x42x22.5mm(1.66x1.66x0.89in), Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, Installation hole distance 31mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 143g.
• Performance Data: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.16Nm (22.66oz·in), Resistance 4.2Ω, Rated current 0.8A, Rotor inertia approx 23g.cm², Inductance 4.3mH±20%.
• Safety Specifications: With safe and reliable operation, this Nema 17 Step 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 temperature 15%RH～95%RH-20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• ​Exceptionally Quiet Powerhouse: 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.
• Key Details: 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). 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.
