상품 특징

• Size Specifications: Nema 17 closed-loop stepper motor with integrated driver dimensional parameters are as follows. Body size 42x42x82mm (1.66x1.66x3.23in), Shaft length 22.5mm, Shaft diameter Ø5mm, D-cut length 18mm, Installation hole distance 31mm, Black (A+) Green (A-) Red (B+) Blue (B-), with Cable 0.3M, Weight 529g.
• Performance Data: Nema 17 Closed Loop Stepper Motor with built-in driver, 2 Phase, Step angle 1.8‌dge(200 steps/rev), Holding torque 0.7Nm (99.13oz·in), Resistance 1.5Ω, Rated current 2.0A, Rotor inertia approx 78g.cm², Inductance 2.3mH±20%.
• Operational Safety: This Nema 17 Step motor with integrated closed-loop controller 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; Temperature rise 80K MAX; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Smooth, Powerful Drive: Leveraging reinforced steel cores and meticulously wound coils, this Nema 17 Closed Loop Stepper Motor with Closed Loop Stepper Controller offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
• Key Details: Higher speed leads to a reduction in torque, with operation closed-loop up to 1800 RPM. Lower current reduces both torque and temperature rise, and lower voltage decreases torque (optimal range: 12–24V DC). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 42mm Closed Loop Stepper Motor with Closed Loop Stepper Driver is compact yet provides high torque for heavy-duty tasks.
