The Omron R88MK3K020FBS2 is a G5-series servo motor delivering 14.3 Nm of torque at 2000 min⁻¹, drawing 8.7 A rated current across a 323–528 V operating window. Frame dimensions are 225 mm wide by 176 mm tall by 176 mm deep — a compact footprint for a motor in this torque class, sized for direct mounting to a machine frame or a servo-driven axis.
What the Ratings Mean for Fit
The 14.3 Nm torque at 2000 min⁻¹ tells you this motor is sized for moderate-to-heavy rotary loads — think indexing tables, conveyor drives, or spindle axes where the inertia and breakaway torque demand that output. The 8.7 A rated current is the thermal limit at full load; the drive supplying it must be capable of that continuous current plus peak transient for acceleration. The 323–528 V operating range covers standard three-phase supplies from 400 VAC class through 480 VAC, with headroom for line sag. Frame dimensions (225 x 176 x 176 mm) dictate the mounting footprint and coupling envelope — verify shaft dimensions and pilot diameter against your existing mechanical interface before committing the BOM.
