상품 특징

• Specifications: Nema 17 Stepper Motor has the following various dimensional parameters. Body size 42x42x20.5mm(1.66x1.66x0.81in), 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 124g.
• Performance Data: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Resistance 4.2Ω, Rated current 1.0A, Rotor inertia approx 16.5g.cm², Inductance 3.4mH±20%.
• Safety: This 42 Stepper Motor boasts safe and reliable operation, with 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 -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Important Notes: 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 used in 3D printers, DIY robots, CNC machines, and other automated systems. Its compact size and high torque suit demanding applications.
• More Power, Less Noise: 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.
