The Yaskawa SGM7J-08AFA61 is a 750 W Sigma-7 medium-inertia rotary servo motor for accurate, high-speed industrial positioning. It delivers a rated torque of 2.39 Nm at 3000 RPM and an instantaneous maximum torque of 8.36 Nm.
The motor incorporates a 24-bit incremental serial encoder and a straight output shaft with key and threaded center hole. The final 61 configuration does not include a holding brake or oil seal.

The SGM7J-08AFA61 is normally matched with a compatible Sigma-7 SERVOPACK such as an SGD7S-5R5A capacity. Final selection must consider the command interface, controller architecture, cable length, regeneration, load inertia and machine safety functions.
Typical applications include packaging equipment, material-handling systems, printing machinery, compact machine tools, semiconductor equipment, indexing systems, robotic positioning axes and automated production machinery.
Verify the complete SGM7J-08AFA61 suffix rather than selecting a replacement only by the SGM7J-08A capacity code. Confirm the incremental encoder, shaft dimensions, keyway, center tap, flange size and connector arrangement.
Check the SERVOPACK model, firmware, motor parameters, encoder cable, power cable, regenerative requirements, coupling and load inertia. Because this version has no holding brake, vertical or suspended loads require a separate mechanical holding method.
Related models include SGM7J-08AFA21 with a plain shaft, SGM7J-08AFA6C with a holding brake, SGM7J-08AFA6S with an oil seal and SGM7J-08A7A61 with a 24-bit absolute encoder.
Please provide the complete nameplate, installed SERVOPACK model, motor and encoder cable numbers, load information and photographs of the shaft and connectors. Availability, condition and included components must be confirmed for the specific offer.
