상품 특징

• Specifications: Through-shaft Nema 11 stepper motor has the following various dimensional parameters. Body size 28x28x31mm (1.11x1.11x1.23in), TR5x1 100mm, Installation hole distance 23mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-), incl. Cable 1M, Weight 139g.
• Parameters: Nema 11 through-shaft linear stepper motor with integrated 100mm tr5, 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 6Ncm (8.5oz·in), Rated current 1.0A, Resistance 2.9Ω, Inductance 1.1mH±20%, Rotor inertia approx 23g.cm².
• Safety: This Nema 11 non-captive stepper 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.
• Exceptionally Quiet Powerhouse: Experience steadier operation with our enhanced Nema 11 Step Motor. Superior steel cores and optimized windings produce up to 20% higher holding torque. Engineered for quiet running, it reduces vibration and environmental sound interference.
• Notes to Remember: As speed rises, torque falls, the recommended speed range is 0–600 RPM. Lower current reduces torque and temperature rise, and lower voltage results in less torque (12–24V DC range). The 28mm Stepper Motor with TR5x1 is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
