R88M-G20030H-S2 - Omron G-series 200 W AC servo motor

Documented AC servo-motor role for R88M-G20030H-S2, with source-backed evidence and explicit installation boundaries.

Documented function

Rebuilt from individual evidence

System position

Unknown: Evidence boundary

Omron identifies R88M-G20030H-S2 as a G-series 200 W AC servo motor rated at 3000 r/min.

The motor uses an incremental encoder and has a straight shaft with key and tap.

Omron lists a rated torque of 0.64 Nm and peak torque of 1.78 Nm for the exact motor.

The motor sits downstream of its servo drive and upstream of the machine axis or load.

The incremental encoder supplies rotor feedback to the servo control loop.

Unknown: The installed servo drive, feedback wiring, firmware, machine load, and site-specific compatibility are not established by the captured sources.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Drives a controlled machine axis with the documented servo torque and speed.
System position: Sits downstream of its servo drive and upstream of the machine axis or load.
Upstream / inputs: Receives electrical power and motion commands from the matched servo drive.
Downstream / outputs: Delivers rotary torque and incremental encoder feedback to the servo system.
Limitations: Unknown: The installed servo drive, feedback wiring, firmware, machine load, and site-specific compatibility are not established by the captured sources.
