This NEMA 34 hollow-shaft stepper motor (86HS76-4004H15S) delivers 4.5 N·m (639 oz·in) of holding torque in an 86 × 86 mm frame with a 76 mm body length. It features a 1.8° step angle, 4.0 A rated current per phase, 4-wire bipolar wiring, and a double shaft design: a hollow front shaft with Φ20 mm outer diameter and Φ15 mm inner bore (10 mm length, with a 3 × 5 mm slot) plus a 3 mm rear shaft, operating on 24–110 VDC and weighing 2.5 kg. The Φ15 mm through-hole allows cables, tubing, shafts, or optical components to pass directly through the motor centerline, making it well suited to high-torque rotary stages in semiconductor manufacturing, robotic arm joints, CNC indexing tables, packaging machinery, and pick-and-place systems that require integrated cable or pneumatic routing through the rotation axis. The matched drive is OK2D872.
