The Yaskawa SGM7A-04AFA21 is a 400 W Sigma-7 low-inertia rotary servo motor with a straight output shaft without a keyway. It is designed for precision motion axes that use clamping, compression or shrink-fit coupling systems.
The motor provides a rated torque of 1.27 Nm at 3000 RPM and supports a maximum motor speed of 6000 RPM. It incorporates a 24-bit incremental serial encoder and is supplied without a holding brake or oil seal.

The SGM7A-04AFA21 is normally matched with a compatible Sigma-7 SERVOPACK in the SGD7S-2R8A capacity class. The complete drive model must be selected according to the controller interface, communication system, safety functions and machine requirements.
Typical applications include electronic assembly systems, semiconductor machinery, inspection equipment, compact packaging machines, printing systems, indexing mechanisms and robotic positioning axes.
The output shaft does not include a keyway. Confirm that the installed coupling is designed for a plain shaft and provides sufficient clamping force without damaging or distorting the shaft.
Do not directly substitute the keyed-shaft SGM7A-04AFA61 without checking the coupling, shaft engagement and mechanical assembly. Verify the complete suffix, encoder, flange, connectors, SERVOPACK, firmware, motor parameter file and cable set.
This model does not include a holding brake. Vertical axes and suspended loads require a separate mechanical holding system.
Related models include SGM7A-04AFA61 with a keyed and tapped shaft, SGM7A-04AFA2C with a plain shaft and holding brake, SGM7A-04A7A21 with an absolute encoder and SGM7A-04A7A61 with an absolute encoder and keyed shaft.
Please provide the complete motor nameplate, installed SERVOPACK model, coupling design, motor and encoder cable numbers and photographs of the shaft and connectors. Product availability, condition and supplied components must be confirmed for each quotation.
