The 240 VAC input means it runs on a standard single-phase line without a step-down transformer, common in smaller machine cells. The absolute encoder eliminates the need for a homing sequence on power-up; position is retained through a cycle, which saves time on multi-axis lines. No brake means the load must hold itself or be held by an external brake — the motor alone will not lock the shaft when power drops. The oil-tight seal makes it suitable for environments with cutting fluids or light washdown, though not submersion-rated. ## Deployment context The cylindrical body with key and tap mounts in a standard clamp or face-mount bracket — no custom flange needed. The absolute encoder communicates position over the 1S servo drive's serial link; wiring is a single feedback cable back to the drive. The oil-tight seal allows installation in a machine tool enclosure where coolant mist is present, but the motor itself is not rated for submersion.","metaTitle":"Omron R88M-1M1K020T-OS2 Servo Motor, 1 kW, 2000 rpm, 240 VAC","metaDescription":"Omron R88M-1M1K020T-OS2 1S servo motor, 1 kW, 2000 rpm, 240 VAC, absolute encoder, no brake.
