상품 특징

• Dimensional details: The physical dimensions of a Through-shaft Nema 17 stepper motor are summarized below. Body size 42x42x59mm (1.66x1.66x2.33in), TR8x8 350mm, Installation hole distance 31mm, 4-Wire, Black (A+) Green (A-) Red (B+) Blue (B-), Cable 1M, Weight 591g.
• Specifications: Nema 17 through-shaft linear stepper motor with integrated 350mm t8 , Step angle 1.8‌dge(200 steps/rev), 2 Phase Holding torque 0.7Nm (99.13oz·in), Resistance 1.5Ω, Rated current 2.5A, Inductance 2.3mH±20%, Rotor inertia approx 78g.cm².
• Safety Specifications: This Nema 17 non-captive stepper motor boasts safe and reliable operation, 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].
• Precision-Built for Higher Output: Choose our upgraded Nema 17 Stepper Motor for increased holding torque and remarkably quiet function. Re-engineered steel cores and precision windings minimize noise, contributing to smoother overall system operation with less environment disruption.
• Things to Note: 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). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor with T8 compact size and high torque are perfect for a variety of demanding applications.
