Anaheim Automation 34D307D 4.5VDC Stepper Motor

Anaheim Automation's 34D307D-LW8 is a NEMA 34 frame, four‑phase hybrid stepper motor in the 34D Series, designed for precise, repeatable rotation in automation, CNC and robotics applications. This bipolar stepper delivers 1.8° per‑step resolution and is specified at 2.5 A RMS per phase with a 6.45 V RMS drive voltage, featuring 28 mH inductance per phase to support stable current control. The LW8 variant uses eight leads and a double shaft, with a body length of 5.3 inches, overall weight around 7.8 lb, and rotor inertia of 0.0285 oz·in·s², enabling rapid, controlled motion in compact packages. Maximum bipolar torque is listed at 630 oz‑in, making it suitable for demanding positioning tasks where precise torque and detent torque characteristics matter.
