The R88M1M40030HBS2: Operating voltage range is 170–264 VAC, which covers nominal 200 V and 240 V single-phase or three-phase lines with tolerance for brownout conditions down to 170 V. The 134 mm width, 60 mm height, and 60 mm length define a compact square-frame motor that fits in tight axis clusters — the 60 mm depth is the body length excluding the output shaft and encoder connector.
The 1S series is Omron's compact servo line, positioned between the legacy R88M-K series and the high-performance R88M-G series. The R88M1M40030HBS2 is the 400 W class frame (1.27 Nm at 3000 min⁻¹), sharing the same 60 mm square body as the 200 W and 750 W siblings. The difference is the winding and magnet stack — the 400 W variant draws 2.5 A versus 1.6 A for the 200 W version, so the drive's continuous current rating is the deciding factor when swapping between frame sizes.
