The R88M‑K75030H‑S2 is part of Omron’s Accurax G5 family of AC servo motors, intended for high‑speed, high‑precision motion control where the counterpart R88D‑KN08H‑ECT (or similar G5 drive) supplies the power and control signals. The motor delivers 0.75 kW output at 3000 rpm, with a continuous torque of 2.4 Nm and a peak torque of 7.1 Nm, allowing short‑burst acceleration for rapid positioning tasks such as tool‑changer indexing, conveyor acceleration, and robotic‑arm moves. The 20‑bit incremental encoder provides high‑resolution position feedback suitable for interpolated CNC axes and synchronized multi‑axis motion using pulse‑train, analog, MECHATROLINK‑II, or EtherCAT control methods.
Mechanically, the motor has a cylindrical frame with an 80‑mm square flange and a 19 mm straight shaft featuring a key and tap (keyway and threaded hole), enabling direct belt‑drive, gearbox, or pulley attachment without additional machining. The unit is supplied without electromagnetic brake or oil‑seal, so it is typically used in vertical‑load‑supported or horizontally‑oriented applications where external brakes or mechanical stops handle holding torque. The unpacked weight is about 2.3 kg, and the motor is constructed to IP67 protection and industrial EMC standards, making it suitable for integration into CNC spindles, feed‑axis tables, and packaging‑machine rotary stages.
From a system‑integration standpoint, the R88M‑K75030H‑S2 is designed for “plug‑and‑run” compatibility with Omron G5 drives: parameters are often auto‑configured or set via software, with no manual motor‑parameter tuning required once the physical connection is made. The motor supports low‑speed ripple and low‑torque‑cogging performance, which is important for smooth contouring in CNC applications and quiet operation in food‑ and packaging‑handling equipment. Typical use cases include CNC machine‑tool axes, labeling machines, pick‑and‑place robots, and high‑speed rotary‑cutting platforms, where precise, repeatable motion at medium power levels is required.
