Product Overview

The Yaskawa SGM7J-01AFA21 is a compact 100 W Sigma-7 medium-inertia rotary servo motor designed for small industrial positioning axes. It delivers a rated torque of 0.318 Nm at 3000 RPM and supports a maximum speed of 6000 RPM.

This exact configuration uses a 24-bit incremental serial encoder and a straight shaft without a key. The final 21 designation identifies a version without a holding brake or oil seal.

Main Features

100 W rated output for compact automation equipment.
Medium-inertia rotor for stable load matching.
Rated torque of 0.318 Nm and instantaneous maximum torque of 1.11 Nm.
Rated speed of 3000 RPM and maximum speed of 6000 RPM.
24-bit incremental serial encoder.
Straight output shaft without a keyway.
Compact 40 mm flange-class construction.
No holding brake or oil seal.

Compatible System and Applications

The SGM7J-01AFA21 is typically paired with a compatible 100 W Sigma-7 SERVOPACK such as an SGD7S-R90A configuration. Final selection depends on the control interface, encoder support, cable set and controller architecture.

Typical applications include small feeders, inspection devices, electronic assembly machines, labelling systems, compact positioning stages, measuring equipment and light robotic mechanisms.

Maintenance and Replacement Notes

The straight shaft has no keyway, so the coupling must use a compatible clamping, compression or shrink-fit arrangement. Do not assume that it is mechanically interchangeable with SGM7J-01AFA61, which has a keyed and tapped shaft.

Confirm the full suffix, shaft diameter, shaft length, flange, encoder type, connector orientation, SERVOPACK capacity, firmware and cable part numbers. This model has no holding brake and should not directly support a suspended load after servo power is removed.

Related Models

Related models include SGM7J-01AFA61 with a keyed and tapped shaft, SGM7J-01AFA2C with a holding brake, SGM7J-01AFC6S with an oil seal and SGM7J-02AFA21 in the 200 W class.

Inquiry and Supply Notes

Please provide the complete motor nameplate, SERVOPACK model, coupling design, cable part numbers and photographs of the shaft and connectors. Product condition and supplied accessories must be confirmed in the individual quotation.
