상품 특징

• Specifications: Dimensional parameters of Nema 17 stepper motor with integrated stepper controller are as follows. Body size 42x42x64mm (1.66x1.66x2.52in), Shaft length 22mm, Shaft diameter φ5mm, D-cut length 18mm, Installation hole distance 31mm, Lead color Black (A+) Green (A-) Red (B+) Blue (B-), Weight 385g.
• Parameters: Nema 17 Stepper Motor with built-in driver, 2 Phase, Step angle 1.8‌dge(200 steps/rev), Holding torque 0.55Nm (77.89oz·in), Rated current 1.7A, Resistance 1.8Ω, Inductance 3.4mH±20%, Rotor inertia approx 68g.cm².
• Safety Data: The safe and reliable operation of this Nema 17 Step Motor with Integrated controller is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Temperature rise 80K MAX.
• Smarter Core Design: 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.
• Important Details: 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). The 42mm Stepper Motor with Stepper Driver is perfect for 3D printers, DIY robots, CNC machines, and other automated systems, offering a compact size and high torque for demanding tasks.
