Motor identity and key ratings
The Omron R88M1M5K515CBS2 is a 1S-series servo motor delivering 35 Nm of rated torque at 1500 min⁻¹ output speed, drawing 14 A at full load. The 35 Nm rating tells you the motor can hold or accelerate a load with that much rotational force continuously — not just peak. 1500 min⁻¹ is the base speed for this frame, meaning the motor delivers full torque up to that speed; above it you're in the constant-power field-weakening region. Operating voltage range is 323–528 VAC, which covers standard 400 VAC three-phase supplies with headroom for 480 VAC lines common in North American panels. The 14 A rated current is the continuous RMS draw at rated torque — size your servo drive and cable for at least this, plus margin for peak transients during acceleration.
Frame dimensions and mounting
The motor measures 295 mm wide, 180 mm high, and 180 mm deep. That 295 mm width is the overall envelope including the connector housing — check your cabinet clearance and cable-bend radius before panel layout. The 180 mm square frame suggests a flange-mount pattern typical of this torque class; verify the pilot diameter and bolt circle from the dimensional drawing before cutting the mounting plate.
