The Omron R88M1M20030HBS2 is a 1S series servo motor delivering 637 Nmm of rated torque at 3000 min⁻¹ output speed, drawing 1.5 A from a 170–264 VAC supply. The 1S family is Omron's compact, high-resolution servo line, typically paired with the 1S-series drive for closed-loop positioning on pick-and-place, packaging, and assembly lines. The 108 mm width, 60 mm height, and 60 mm length frame fits the standard 1S mounting pattern — verify the drive-side connector and encoder feedback cable match your existing harness before committing the BOM line.
637 Nmm (0.637 Nm) is the continuous stall torque — the load the motor can hold at zero speed without overheating. For a direct-drive application, that moves a small belt conveyor or a rotary index table carrying a few kilograms; for a ballscrew-driven axis, it translates to a thrust force that depends on the screw lead. 3000 min⁻¹ is the rated speed, typical for a medium-speed servo — fast enough for most pick cycles, not a high-speed spindle replacement. The 1.5 A rated current is the continuous RMS draw at rated torque; the drive's peak current setting (typically 2–3× rated) handles acceleration transients. Operating voltage range of 170–264 VAC means the motor accepts standard 200–240 V single-phase or three-phase input after the drive's rectifier stage — common in Asian and North American 200 V-class installations. Below 170 V the drive may fault on undervoltage; above 264 V the DC bus exceeds the capacitor rating. The 108 × 60 × 60 mm frame (width × height × depth) determines the bolt pattern and shaft extension — measure the existing mount before ordering a replacement.
