What this motor delivers
The Omron R88M1M75030HBS2 is a 1S-series servo motor rated for 2.39 Nm of continuous torque at 3000 min-1 output speed. It draws 4.6 A at its rated load, operating on a 170–264 VAC supply. That torque figure tells you what it can hold on a constant-speed axis — think conveyor belts, spindle drives, or indexing tables where you need steady muscle without oversizing the frame.
The motor body measures 153 mm wide by 80 mm tall by 80 mm deep. That 153 mm width is the dimension you'll care most about when fitting it into a tight cabinet or alongside other axes on a gantry — measure that clearance before you cut the mounting plate. The 80 mm square cross-section is standard for this power class, so existing brackets from the 1S family should line up.
