637 Nmm at 3000 min⁻¹ — what it delivers on the axis
The R88M1M20030TS2 is an Omron 1S series servo motor delivering 637 Nmm of rated torque at 3000 min⁻¹ output speed. That torque figure means it can directly drive a small indexing table or a pick-and-place Z-axis without a gearbox — the 3000 min⁻¹ base speed suits most ball-screw and belt-drive applications in the sub-1 kW range. Rated current draws 1.5 A at the 230 V max bus voltage — this sets the drive sizing floor. The 1S drive partner must supply at least that continuous current at the DC-bus voltage the motor sees; a drive undersized on current will current-limit and fault on acceleration profiles.
Frame envelope — 80×60×60 mm
The frame measures 80 mm wide, 60 mm tall, and 60 mm deep. That 80 mm width is the standard small-frame servo footprint — the motor mounts directly to a 60 mm bolt-center pattern, matching the common NEMA 23 or 60-series metric interface. Panel clearance around the connector and feedback cable bend radius adds roughly 25 mm at the rear. The 1S series encoder and power connectors are on the rear face; the cable exits axially. In a tightly packed cabinet, allow 80 mm of free depth behind the motor face for the connector hood and minimum bend radius of the motor power/feedback cables.
