Safety Data: Operating safely and reliably, this Nema 17 Step motor comes with the following key safety parameters. Dielectric strength 500V A.C 1 MINUTE; Insulation class(UL) B (130℃) [266°F]; Insulation resistance 100MΩ MIN; Operation ambient temperature -20℃ ~+50℃ [-4°F~122°F]; Operation ambient humidity ; Temperature rise 80K MAX.
High Torque Low Noise: Engineered for minimal noise interference, our enhanced Nema 17 Step Motor boasts up to 20% greater holding torque through its higher-grade steel core construction and optimized winding technique. Experience smoother machine cycles with less surrounding disruption.
Things to Note: Increasing speed lowers torque, with the recommended range of 0–600 RPM. Lower current results in lower torque and temperature rise, while reduced voltage decreases torque (range: 12–24V DC). In 3D printers, DIY robots, and CNC machines, the 42mm Stepper Motor's compact size and high torque are perfect for a variety of demanding applications.
