• Safety Specifications: This Nema 24 double shaft stepper motor ensures safe and reliable performance, and here are its 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 temperature -20℃～+50℃ [-4°F～122°F]; Operation ambient humidity 15%RH～95%RH.
• Elevate Your Equipment: Engineered for minimal noise interference, our enhanced Nema 24 Dual Shaft Stepper 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.
• Key Details: Increasing speed lowers torque, with the recommended speed range of 0–600 RPM. Lower current decreases both torque and temperature rise, and reduced voltage results in lower torque (24–36V DC range). Commonly used in 3D printers, DIY robots, CNC machines, and other automated systems, the Nema 24 Dual Shaft Stepper Motor is compact yet provides high torque for heavy-duty tasks.
