Through Shaft Nema 11 Stepper Motor TR5x1 300mm 1.8° 2 Phase High Torque 6Ncm(8.5oz·in) Bipolar 1.0A 2.9Ω 31mm 28 Step Motor with T5 300mm Cable 1M for 3D Printer DIY Robot CNC
Specifications: Dimensional parameters of Through-shaft Nema 11 stepper motor are as follows. Body size 28x28x31mm (1.11x1.11x1.23in), TR5x1 300mm, Installation hole distance 23mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-), with Cable 1M, Weight 161g.
Characteristics: Nema 11 through-shaft linear stepper motor with integrated 300mm tr5, 2 Phase, Step angle 1.8 Degree(200 steps/rev), Holding torque 6Ncm(8.5oz·in), Resistance 2.9Ω, Rated current 1.0A, Rotor inertia approx 23g.cm², Inductance 1.1mH±20%.
Safety Compliance: Operating safely and reliably, this Nema 11 non-captive stepper motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation resistance 100MΩ MIN; Insulation class(UL) B (130℃) [266°F]; Operation ambient temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH; Temperature rise 80K MAX.
Smooth, Powerful Drive: 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.
Key Details: 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). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the 28mm Stepper Motor with TR5x1 is compact yet provides high torque for heavy-duty tasks.
