상품 특징

• Dimensional data: Key dimensions for 0.9deg Nema 17 Stepper Motor include the following. Body size 42x42x32.8mm(1.66x1.66x1.3in), Shaft length φ5mm, Shaft diameter 17mm, D-cut length 13mm Installation hole distance 31mm, incl. Cable 1m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 236g.
• Parameters: Nema 17 Stepper Motor 2 Phase, Step angle 0.9 degree (400 steps/rev), Holding torque 16Ncm (22.66oz·in), Rated current 1.2A, Resistance 2.2Ω, Inductance 3.0mH±20%, Rotor inertia approx 41g.cm².
• Safety Data: This Nema17 Step Motor 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.
• More Power, Less Noise: Experience steadier operation with our enhanced Nema 17 Stepper Motors. Superior steel cores and optimized windings produce up to 20% higher holding torque. Engineered for quiet running, it reduces vibration and environmental sound interference.
• Important Notes: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM for. Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (12–24V DC range). The 42mm Stepper Motor is used in 3D printers, DIY robots, CNC machines, and automation systems. Its compact size and high torque suit demanding applications.
