The Yaskawa SGM7J-04A7A21 is a 400 W Sigma-7 medium-inertia rotary servo motor equipped with a 24-bit absolute serial encoder. It is intended for industrial positioning systems that require high-resolution feedback and retention of established machine-position information through a correctly configured absolute encoder system.
The motor provides a rated torque of 1.27 Nm at 3000 RPM and an instantaneous maximum torque of 4.46 Nm. Its final 21 specification identifies a straight shaft without a keyway and without a holding brake or oil seal.

The SGM7J-04A7A21 is intended for a compatible 400 W Sigma-7 SERVOPACK such as an SGD7S-2R8A capacity with the required absolute-encoder support. Final selection depends on the command interface, controller architecture, safety functions, encoder cable and backup arrangement.
Typical applications include indexing systems, packaging machinery, semiconductor equipment, printing machines, compact robots, electronic assembly equipment and precision positioning axes that benefit from absolute position feedback.
Confirm the complete SGM7J-04A7A21 designation, including the absolute encoder and plain-shaft mechanical configuration. Verify shaft diameter, shaft length, coupling method, flange dimensions, connectors and encoder cable.
When installing the motor on another SERVOPACK, review encoder initialization, absolute-position setup, backup requirements, home-offset data, controller coordinates, firmware and motor parameters. Incorrect handling of absolute encoder data can cause loss of the established machine position.
This motor has no holding brake. It must not directly support a vertical or suspended load after servo power is removed unless the machine provides a separate mechanical holding system.
Related models include SGM7J-04A7A61 with a keyed and tapped shaft, SGM7J-04A7A2C with a plain shaft and holding brake, SGM7J-04AFA21 with an incremental encoder and SGM7J-04A7D61 with an absolute encoder and keyed shaft.
Please provide the complete motor nameplate, SERVOPACK model, encoder cable number, controller information, coupling details and photographs of the shaft and connectors. Product condition, encoder status and included accessories must be confirmed for each quotation.
