What the motor delivers
The Omron R88MK2K030FBS2 is a brushless AC servo motor from the G5 family — a medium-inertia rotor sized for packaging, indexing, and general motion axes that need crisp step response without overshoot. Continuous torque is 6.37 Nm at a rated speed of 3000 min⁻¹ and a continuous phase current of 5.7 A, which sets the working point of the motor on the drive's torque/speed curve. Operating voltage envelope is 323 V to 528 V, matching a 400 V-class three-phase DC bus; the drive selection has to land inside that window or the motor's back-EMF will clip the bus at top speed.
Footprint and panel fit
The body is 206 mm wide, 100 mm tall, and 100 mm long — a square-ish housing that drops into a standard G5 mounting footprint with the matched shaft seal and coupling on the front face.
Lifecycle stage is flagged as eol_hot on the manufacturer's record — the part is in a wind-down phase, so open-market availability is going to thin out as stock draws down. For a panel builder or MRO planner specifying this motor into a BOM, the practical move is to quote the residual stock against an RFQ now and decide whether a confirmed working quantity gets locked in before the channel empties.
