Yaskawa SGM7J-08AFC6E Sigma-7 750W Servo Motor with Brake and Oil Seal
| Place of Origin | USA |
| Brand Name | YASKAWA |
| Model Number | SGM7J-08AFC6E |
Product Overview
The Yaskawa SGM7J-08AFC6E is a 750 W Sigma-7 medium-inertia rotary servo motor equipped with a 24-bit incremental encoder, 24 VDC holding brake and oil seal. It is designed for higher-load positioning axes requiring accurate motion control and mechanical load retention when servo power is removed.
The motor delivers a rated torque of 2.39 Nm at 3000 RPM and an instantaneous maximum torque of 8.36 Nm. Its medium-inertia design is suitable for applications where stable load matching is as important as rapid acceleration and precise positioning.
Main Features
- 750 W rated output for 200 VAC-class Sigma-7 systems.
- 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.
- Integrated 24 VDC holding brake.
- Oil seal for additional shaft-side environmental protection.
- Straight shaft with key and threaded center hole.
- IP67 protective structure under the specified installation conditions.

Compatible System and Applications
The SGM7J-08AFC6E is typically matched with a correctly configured Sigma-7 SERVOPACK such as an SGD7S-5R5A capacity. Final selection must consider the control interface, regeneration, cable length, load inertia and required safety functions.
Applications include vertical packaging axes, material-handling equipment, compact machine tools, printing machinery, robotics, semiconductor systems and automated production equipment that requires both precise motion and holding-brake functionality.
Maintenance and Replacement Notes
The holding brake is designed to hold a stationary load and must not be used as a normal dynamic stopping brake. Verify the external 24 VDC brake power supply, brake release sequence, suppression circuit and controller interlock before operation.
Confirm the complete SGM7J-08AFC6E model, encoder type, oil seal, shaft geometry, flange dimensions and cable connectors. Check the matched SERVOPACK, firmware, motor parameters, regenerative requirements, load inertia and cabinet safety system. Oil-seal configurations may require derating under specified operating conditions.
