Dimension Specs: Nema 17 Stepper Motor dimensional parameters are as follows. Physique dimension 42x42x20.5mm, (1.66×1.66×0.81in), Set up gap distance 31mm, Shaft size 24±0.5mm, Shaft diameter φ5mm, D-cut size 24mm, Cable 1m, 4-Wire Black (A+) Inexperienced (A-) Purple (B+) Blue (B-), Weight 124g.
Traits: Nema 17 pancake stepper motor 2 Part, Step angle 1.8‌dge (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Rated present 1.0A, Resistance 4.2Ω, Inductance 3.4mH±20%, Rotor inertia approx 16.5g.cm².
Operational Security: Working safely and reliably, this Nema 17 Step motor comes with the next key security parameters. Dielectric energy 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity 15percentRH～95percentRH; Insulation class(UL) B (130℃) [266°F]; Temperature rise 80K MAX.
Key Factors: As velocity rises, torque falls, the advisable velocity vary is 0–600 RPM. Decrease present reduces torque and temperature rise, and decrease voltage leads to much less torque (12–24V DC vary). Broadly utilized in 3D printers, DIY robots, CNC machines, and different automated programs, the 42mm Stepper Motor provides compact dimension and excessive torque for robust duties.
Important Torque Improve: Providing as much as 20% extra holding torque than typical Nema 17 Step Motor, our model focuses on low-noise operation. Its enhanced metal core and winding design guarantee clean movement and considerably decreased sound emission.
