상품 특징

• Dimensional data: Key dimensions for Nema 34 Stepper Motor include the following. Body size 86x86x94.5mm(3.39x3.39x3.73in), Shaft length 32±0.5mm, Shaft diameter φ14mm, Key5*5*25mm, Installation hole distance 69.6mm, Cable 2m, 4-Lead Black (A+) Green (A-) Red (B+) Blue (B-), Weight 3039g.
• Specifications: Nema 34 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 7.4Nm (1047.93oz·in), Resistance 0.6Ω, Rated current 5.5A, Rotor inertia approx 2100g.cm², Inductance 4.2mH±20%.
• Safety Data: This 86mm Step Motor boasts safe and reliable operation, with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
• Smooth, Powerful Drive: 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.
• Key Points: 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). Widely used in 3D printers, DIY robots, CNC machines, and other automated systems, the 86mm Stepper Motor offers compact size and high torque for tough tasks.
