Nema 17 Closed Loop Stepper Motor with Integrated Closed Loop Stepper Driver 1.8° 2 Phase High Torque 0.55Nm(77.89oz·in) Bipolar 2.0A 1.5Ω 71mm Cable 0.3M for 3D Printer DIY Robot
Specifications: Nema 17 closed-loop stepper motor with integrated driver has the following various dimensional parameters. Body size 42x42x71mm (1.66x1.66x2.8in), Shaft length 23mm, Shaft diameter Ø5mm, D-cut length 18mm, Installation hole distance 31mm, Black (A+) Green (A-) Red (B+) Blue (B-), Cable 0.3M, Weight 408g.
Parameters: Nema 17 Closed Loop Stepper Motor with built-in driver, 2 Phase, Step angle 1.8 Degree(200 steps/rev), Holding torque 0.55Nm (77.89oz·in), Rated current 2.0A, Resistance 1.5Ω, Inductance 3.0mH±20%, Rotor inertia approx 68g.cm².
Safety: This Nema 17 Step motor with integrated closed-loop controller operates safely and reliably. 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 temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
High Torque Low Noise: 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.
Important Considerations: 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). The 42mm Closed Loop Stepper Motor with Closed Loop Stepper Driver is used in various applications like 3D printers, DIY robots, and CNC machines, offering a compact design and high torque for demanding tasks.
