상품 특징

• Dimensional details: The physical dimensions of a Nema 17 stepper motor with integrated stepper controller are summarized below. Body size 42x42x76mm (1.66x1.66x3in), Shaft length 22mm, Shaft diameter φ5mm, D-cut length 20mm, Installation hole distance 31mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), Weight 506g.
• Specifications: Nema 17 Stepper Motor with built-in driver, Step angle 1.8‌ Degree(200 steps/rev), 2 Phase Holding torque 0.7Nm (99.13oz·in), Resistance 1.5Ω, Rated current 2.5A, Inductance 2.3mH±20%, Rotor inertia approx 78g.cm².
• Safety: This Nema 17 Step Motor with Integrated controller ensures safe and reliable performance, and here are its key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～122°F].
• Advanced Steel Construction: Leveraging reinforced steel cores and meticulously wound coils, this Nema 17 Stepper Motor with Stepper Driver offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
• Key Information: Higher speed leads to a reduction in torque, with operation recommended at 0–600 RPM. Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 12–24V DC). Used in 3D printers, DIY robots, CNC machines, and other systems, the 42mm Stepper Motor with Stepper Driver's compact size and high torque make it suitable for tough applications.
