YEJMKJ Through Shaft Nema 17 Stepper Motor TR8x8 300mm 42x34mm 0.3Nm 1.5A

Key features

• Dimensional details: The physical dimensions of a Through-shaft Nema 17 stepper motor are summarized below. Body size 42x42x34mm (1.66x1.66x1.34in), TR8x8 300mm, Installation hole distance 31mm, 4-Lead, Black (A+) Green (A-) Red (B+) Blue (B-), with Cable 1M, Weight 340g.
• Characteristics: Nema 17 through-shaft linear stepper motor with integrated 300mm t8 , 2 Phase, Step angle 1.8‌ Degree(200 steps/rev), Holding torque 0.3Nm (42.48oz·in), Resistance 2.7Ω, Rated current 1.5A, Rotor inertia approx 48g.cm², Inductance 4.7mH±20%.
• Safety: Operating safely and reliably, this Nema 17 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]; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～122°F].
• Safety: Operating safely and reliably, this Nema 17 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]; Temperature rise 80K MAX; Operation ambient humidity 15%RH～95%RH; Operation ambient temperature -20℃～+50℃ [-4°F～123°F].
• Important Details: Faster speeds reduce torque, with operation recommended at 0–600 RPM. Lower current reduces torque and temperature rise, and lower voltage also reduces torque (ideal voltage range: 12–24V DC). The 42mm Stepper Motor with T8 is perfect for 3D printers, DIY robots, CNC machines, and other automated systems, offering a compact size and high torque for demanding tasks.
