Traits: Nema 17 Stepper Motor 2 Part, Step angle 1.8‌ Diploma (200 steps/rev), Holding torque 0.47Nm (66.56oz·in), Rated present 1.7A, Resistance 1.7Ω, Inductance 3.5mH±20%, Rotor inertia approx 60g.cm².
Measurement Specs: Nema 17 Stepper Motor dimensional parameters are as follows. Physique dimension 42x42x37.5mm(1.66×1.66×1.48in), Shaft size 24±0.5mm, Shaft diameter φ5mm, D-cut size 24mm, Set up gap distance 31mm, Cable 1m, 4-Lead Black (A+) Inexperienced (A-) Purple (B+) Blue (B-), Weight 291g.
Security Specs: This Nema17 Step Motor operates safely and reliably. Listed here are its key security parameters: Dielectric energy 500V A.C 1 MINUTE; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15percentRH～95percentRH; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
Exceptionally Quiet Powerhouse: Constructed with superior metal cores and exactly tuned windings, this Nema 17 Step Motor generates as much as 20% stronger holding torque whereas considerably lowering noise output. Obtain smoother machine movement and decrease acoustic influence.
Key Particulars: With greater speeds, torque decreases. The best vary for operation is 0–600 RPM, and as much as 1800 RPM for closed-loop programs. Decrease present ends in diminished torque and temperature rise, whereas decrease voltage reduces torque (advisable: 12–24V DC). Generally utilized in 3D printers, DIY robots, CNC machines, and different automated programs, the 42mm Stepper Motor is compact but gives excessive torque for heavy-duty duties.
