The Omron R88MK3K020FS2 is a G5 Series servo motor delivering 14.3 Nm of torque at a rated speed of 2000 min⁻¹, drawing 8.7 A from a 323-528 VAC supply. It is sized for applications requiring a compact 176 mm cube frame (176 mm height × 176 mm length) with a 196 mm width — typical for a medium-torque axis on a packaging, material handling, or assembly line.
The 14.3 Nm torque at 2000 min⁻¹ places this motor in the medium-torque, moderate-speed band — enough to drive a direct-coupled load like a conveyor roller or a rotary index table without a gearbox, but not sized for high-inertia or high-speed spindle work. The 8.7 A rated current at 323-528 VAC tells the drive selection engineer what the continuous RMS current draw is; the drive must be sized to supply at least that current continuously, plus headroom for peak torque demands during acceleration. The 176 mm cube frame with 196 mm width fits standard NEMA or metric mounting patterns in the G5 series — verify bolt-hole spacing against the existing bracket before committing the swap.
