Yaskawa SGM7J-08AFC6S Sigma-7 750W Medium-Inertia Servo Motor with Oil Seal
Product Overview
The Yaskawa SGM7J-08AFC6S is a 750 W Sigma-7 medium-inertia rotary servo motor designed for precise industrial positioning and stable load matching. It provides a rated torque of 2.39 Nm at 3000 RPM and supports a maximum speed of 6000 RPM.
This configuration incorporates a 24-bit incremental serial encoder, a straight shaft with key and tap and an oil seal. The final S option identifies an oil-seal version without a holding brake.
Main Features
- 750 W rated output for 200 VAC-class Sigma-7 systems.
- Medium-inertia rotor for responsive yet stable load control.
- Rated torque of 2.39 Nm and instantaneous maximum torque of 8.36 Nm.
- Rated speed of 3000 RPM and maximum speed of 6000 RPM.
- 24-bit incremental serial encoder.
- Straight output shaft with key and threaded center hole.
- Oil seal for additional shaft-side protection.
- No integrated holding brake in the 6S configuration.

Compatible System and Applications
The SGM7J-08AFC6S is typically paired with a correctly configured Sigma-7 SERVOPACK such as an SGD7S-5R5A capacity. Final compatibility depends on the drive interface, encoder support, cable set, controller architecture and regenerative requirements.
Typical applications include packaging machinery, printing equipment, material-handling systems, semiconductor machinery, indexing tables, compact machine tools and robotic positioning axes. Because this model has no holding brake, vertical or suspended loads require a separate load-holding solution.
Maintenance and Replacement Notes
Verify the complete SGM7J-08AFC6S designation, including the C design-revision character and final 6S shaft and option configuration. Confirm the incremental encoder, oil seal, shaft diameter, keyway, threaded center hole, flange and connector orientation.
Check the matched SERVOPACK, firmware, motor parameters, power cable, encoder cable, coupling and load inertia. Oil-seal versions may require output derating under specified operating-temperature and installation conditions.
