The Omron R88M-G40030T-S2 is a 400-watt servo motor from the R88M-G series, a compact rotary motor line used in positioning and motion-control axes on assembly, packaging, and material-handling lines.

What to watch for in a swap
If you're retrofitting a machine that originally carried this motor, the R88M-G family shares a common frame size and feedback connector pattern across the 400 W tier, so a same-series sibling is the cleanest drop-in — no need to re-machine the mount or re-run the feedback cable.
This is a servo motor, so it mates to an Omron servo drive (G-series or later) via a power cable and a separate feedback encoder cable — no fieldbus or I/O on the motor itself. The drive handles the commutation, tuning, and safety functions.
