NEMA 17 Integrated Closed Loop Stepper Motor 42BYGH40

NEMA 17 Integrated Closed Loop Stepper Motor 42BYGH40

The 42BYGH40 combines a 42 × 42 mm flange and 40 mm stack with a built-in 1000 PPR incremental encoder, enabling closed-loop control to prevent missed steps and improve accuracy. It’s wound for 1.5 A per phase with 1.8 Ω (±10 %) phase resistance and 3.6 mH inductance, yielding 0.42 N·m holding torque.

Features

• 1000 PPR (4000 CPR) encoder for closed-loop feedback.
• Rated current 1.5 A per phase, designed for reliable high-current operation.
• Phase resistance 1.8 Ω (±10 %) and inductance ~3.6 mH.
• Holding torque 0.42 N·m for robust static performance.
• Bipolar, two-phase (4‑wire) configuration compatible with standard stepper drivers.
• Closed-loop control reduces heat and improves efficiency compared to open-loop versions.
• Ideal for precision applications requiring feedback and torque stability.
