상품 특징

• Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x20.5mm, (1.66x1.66x0.81in), 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 124g.
• Parameters: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Resistance 4.2Ω, Rated current 1.0A, Inductance 3.4mH±20%, Rotor inertia approx 16.5g.cm².
• Operational Safety: This Nema17 Step Motor operates safely and reliably. Here are its 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].
• Key Points to Remember: Increased speed reduces torque, with operation suggested at 0–600 RPM. A lower current leads to lower torque and temperature rise, and reduced voltage results in lower torque (recommended range: 12–24V DC). The 42mm Stepper Motor is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
• Precision-Built for Higher Output: Leveraging reinforced steel cores and meticulously wound coils, this Nema 17 Step Motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
