Operational Safety: With safe and reliable operation, this Nema 14 Round Step Motor features 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.
Exceptionally Quiet Powerhouse: Engineered for minimal noise interference, our enhanced Nema 14 Round Stepper Motors 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.
Important Details: Increased speed reduces torque, with operation suggested at 0–600 RPM. A lower current leads to lower torque and temperature rise, and reduced voltage results in lower torque (recommended range: 12–24V DC). The 36mm Round Stepper Motor is perfect for 3D printers, DIY robots, CNC machines, and automation systems, offering a compact size and high torque for demanding tasks.
