상품 특징

• Size Specifications: Nema 34 Stepper Motor dimensional parameters are as follows. Body size 86x86x149mm(3.39x3.39x5.87in), 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 5250g.
• Parameters: Nema 34 Stepper Motor 2 Phase, Step angle 1.8‌ Degree (200 steps/rev), Holding torque 12.8Nm (1812.63oz·in), Resistance 0.7Ω, Rated current 6.4A, Inductance 7.2mH±20%, Rotor inertia approx 4000g.cm².
• Safety Specifications: The safe and reliable operation of this 86 Step Motor is supported by these key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃ ～+50℃ [-4°F～122°F]; Temperature rise 80K MAX.
• More Power, Less Noise: Our upgraded Nema 34 Step Motor provides up to 20% higher holding torque. The refined steel core and advanced winding configuration promote efficient, smooth-running mechanics with substantially reduced operational noise for a cleaner working environment.
• Key Information: 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). Used in 3D printers, DIY robots, CNC machines, and other systems, the 86mm Stepper Motor's compact size and high torque make it suitable for tough applications.
