Dimensional data: Key dimensions for Nema 17 Stepper Motor include the following. Body size 42x42x20.5mm, (1.66x1.66x0.81in), Installation hole distance 31mm, Shaft length 24±0.5mm, Shaft diameter φ5mm, D-cut length 24mm, with Cable 1m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 124g.
Parameters: Nema 17 pancake stepper motor 2 Phase, Step angle 1.8dge (200 steps/rev), Holding torque 0.13Nm (18.41oz·in), Resistance 4.2Ω, Rated current 1.0A, Inductance 3.4mH±20%, Rotor inertia approx 16.5g.cm².
Operational Safety: This Nema17 Step Motor operates safely and reliably. Here are its 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 humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F].
Key Points to Remember: Increased speed reduces torque, with operation suggested at 0–600 RPM. A lower current leads to lower torque and temperature rise, and reduced voltage results in lower torque (recommended range: 12–24V DC). The 42mm Stepper Motor is widely used in 3D printers, DIY robots, CNC machines, and more. Its compact design and high torque make it ideal for tough applications.
Precision-Built for Higher Output: Leveraging reinforced steel cores and meticulously wound coils, this Nema 17 Step Motor offers up to 20% increased holding torque versus standard units. Benefit from a quieter operational profile and minimal environmental disturbance.
