The Omron R88M-K3K030F-BOS2 is a 3 kW cylindrical servo motor from the Accurax G5 series, rated for 3000 rpm on a 3-phase 480 VAC supply. It carries an integral holding brake and an incremental encoder, with an oil-tight seal and key-and-tap shaft.
What the ratings mean for fit
The 3 kW continuous rating at 3000 rpm sets the torque curve — match it to the load inertia and duty cycle, not just the nameplate motor power. The integral brake holds the shaft at zero speed when de-energized, critical for vertical-axis loads or any axis that must not drift on power loss. The incremental encoder provides position and velocity feedback to the drive; it loses absolute position on power cycle, so homing is required at each startup. The oil-tight seal and cylindrical body suit it for direct mounting in machined bores or clamp couplings in environments with cutting fluids or washdown mist — but the seal is oil-tight, not IP69K, so high-pressure washdown is outside its design envelope.
