What this motor delivers on the shaft
The Omron R88MK1K530FS2 is a G5-series servo motor rated 4.77 Nm continuous torque at 3000 min-1 output speed, drawing 4.2 A — the rating that has to be matched against the load's reflected inertia and the duty cycle before it goes on the BOM. Bus voltage envelope is 323 V to 528 V, so it pairs with the matching G5 servo drive on a 400 V or 480 V DC-bus supply without an external step-up — check the drive's DC-bus rating against the 528 V ceiling before stacking long cable runs.
Frame and what drops into the panel
Frame size is 160 mm wide by 100 mm tall by 100 mm long, the square-flange footprint common to this G5 power band — the bolt circle and shaft diameter follow the series standard, so a like-for-like swap stays within the existing machine bracketry. On the controls side it is a pure servo motor: feedback resolver/encoder and power feed come back to the G5 drive over the standard G5 cable set, so the commissioning sequence is drive first, motor second, then the autotune pass.
Lifecycle status and how it is sourced
The part is flagged with EOL — last-time-buy posture from the manufacturer, with supply routed through independent distribution rather than the factory-direct channel; availability and quantity are confirmed at RFQ rather than carried as stock. For an installed machine this means treat any new build as a constrained BOM line: confirm hold quantity against the panel's spares policy before release, and pin down whether the drive side (the G5 amplifier) is on the same lifecycle clock — the motor without a supported drive is a stranded asset.
