• Safety Specifications: This Nema 34 Step motor with closed-loop controller kit 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～123°F].
• Notes to Remember: Faster speeds lead to lower torque, with recommended up to 1800 RPM for closed-loop. Lower current reduces torque and temperature rise, while lower voltage decreases torque (recommended range: 48–80V DC). The Nema 34 Closed Loop Stepper Motor Kit with Closed Loop Stepper Driver is ideal for 3D printers, DIY robots, CNC machines, and other other automated systems, with compact size and high torque for complex tasks.
