The Omron R88M-K1K520C-BS2 is a 1.5 kW Accurax G5 servo motor in a cylindrical frame, rated for 2000 rpm on a 3-phase 480 VAC supply. It ships with an integrated holding brake and an absolute encoder — the brake holds the load at power-off, so vertical-axis applications don't back-drive the gearbox on a power loss.
The cylindrical body with key and tap means the motor mounts to a standard NEMA or metric face flange; the keyed shaft transmits torque directly to the load coupling. The absolute encoder eliminates the need for a home-search routine on power-up — the position is known immediately, which saves cycle time on pick-and-place or rotary-indexing stations.
Part of the Accurax G5 series, which Omron positioned as a compact, high-torque-density servo line with smart connectors for faster panel wiring. The 1.5 kW rating at 2000 rpm suits it for medium-duty conveyor drives, spindle positioning, and packaging-machine axes where the load inertia is moderate.
