What this motor is and what it fits
The Omron R88M-K40030L-S2 is a 400 W servo motor from the OMNUC G5-Series, rated for 100 VAC input and 3000 r/min rated speed. It ships with key and tap — meaning the shaft key and the mating tap for the encoder connector are included, so you don't need to chase those as separate line items on a rebuild or retrofit.
