Servo on a machine-tool spindle — the G5 frame at 2.4 Nm
The R88MK75030HBS2 is an Omron R88M-series AC servo motor from the G5 line, sized for mid-range motion axes — 2.4 Nm of rated torque at 3000 min⁻¹, drawing 4.1 A on the DC bus (cite: cite: cite:). That combination matches the profile of a feed axis or indexing table on a packaging or light machine-tool line, where the peak torque envelope above the 2.4 Nm figure does most of the acceleration work during a move profile. The motor is designed to run from the matching G5-series servo drive on a 170–264 V DC-link supply, which is the operating envelope most 200/230 V single-phase or three-fed drive buses land on once rectified (cite: cite:). Sizing a replacement means holding both the torque/speed curve and the bus-voltage band; a 400 V-class drop-in will not run off the same drive without a transformer front-end.
Frame dimensions and panel-side integration
Mechanically the motor is an 80 mm square flange, 199 mm body length (cite: cite: cite:). That footprint is the controlling dimension when matching a gearbox or a pre-machined adapter plate — a substitute has to land on the same 80 mm bolt pattern and stay within roughly the same length envelope, or the coupling alignment and the cabinet cutout both have to be reworked.
