상품 특징

• Dimensional details: The physical dimensions of a Nema 34 Stepper Motor are summarized below. Body size 86x86x77.5mm, (3.39x3.39x3.06in), Installation hole distance 69.6mm, Shaft length 32±0.5mm, Shaft diameter φ14mm, Key5*5*25mm, Cable 2m, 4-Wire Black (A+) Green (A-) Red (B+) Blue (B-), Weight 2367g.
• Parameters: Nema 34 Stepper Motor 2 Phase, Step angle 1.8‌dge (200 steps/rev), Holding torque 5.2Nm (736.38oz·in), Resistance 0.4Ω, Rated current 6.4A, Inductance 2.6mH±20%, Rotor inertia approx 1500g.cm².
• Safety Specifications: Operating safely and reliably, this Nema 34 Step motor comes with the following 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].
• High Torque Low Noise: Offering up to 20% more holding torque than typical Nema 34 Step Motor, our version focuses on low-noise operation. Its enhanced steel core and winding design ensure smooth motion and significantly decreased sound emission.
• Important Notes: Faster speeds lead to lower torque; the recommended operating range is 0–600 RPM. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 48–80V DC). The 86mm Stepper Motor is used in 3D printers, DIY robots, CNC machines, and other automated systems. Its compact size and high torque suit demanding applications.
