Where this 100 W servo drops into the machine
The Omron R88M-KE10030H-S2-Z is an AC servo motor in the compact low-power class — 100 W rated output with 0.16 Nm of rated torque and a 1.1 A armature current, so it pairs naturally with the matching Accurax G5-style drive on small-format indexing tables, lab automation axes, and light pick-and-place gantries where the move profile is short and repetitive rather than continuous-duty. A torque constant of 0.21 Nm/A (±10 %) sets the current-to-force relationship the drive's current loop has to track, and an electrical time constant of 0.79 ms is the figure that governs how aggressively the drive can close that loop before the winding's L/R lag shows up as following error at the shaft.
Shaft load and the 58.8 N thrust budget
The motor's allowable thrust load is 58.8 N — the axial force the front bearing is rated to carry continuously without premature wear — which means a direct-coupled pinion, a small belt drive, or a short zero-backlash coupling sits inside the envelope, while a heavy pulley hanging outboard of the face will push the bearing life down faster than the rated torque curve suggests.
