R7M-A75030-S1 - Omron SMARTSTEP A R7M-A75030-S1 servo motor

Omron SMARTSTEP A R7M-A75030-S1 servo motor. Documented facts, inferred system position, and evidence boundary are recorded for maintenance review.

Documented product role

Rebuilt from individual evidence

System placement

Unknown: Evidence boundary

Omron lists R7M-A75030-S1 as the 750 W cylinder-type AC servo motor with a keyed straight shaft and no brake.

The Omron specification lists the A75030 motor position at 750 W, 3000 rpm, and 2.39 N m rated torque.

The specification pairs the A75030 motor position with the R7D-AP08H servo driver and a 2000-pulse-per-revolution incremental encoder.

R7M-A75030-S1 sits downstream of its matched servo driver and converts controlled electrical power into rotary motion for a machine axis.

Unknown: The installed configuration, wiring, firmware, 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: Converts controlled servo power into rotary motion for the matched machine axis.
System position: Sits downstream of the servo driver as the rotary actuator in the motion system.
Upstream / inputs: Receives controlled three-phase motor power and encoder-related control from the servo driver.
Downstream / outputs: Drives the mechanical axis through its keyed straight shaft and returns incremental position feedback.
Limitations: Unknown: The installed configuration, wiring, firmware, load, and site-specific compatibility are not established by the captured sources.
