Housed direct-drive motor
Yaskawa SGMCS / SGMCV direct drive
Earlier-generation Yaskawa housed direct-drive motors with the load mounted straight onto the rotor face, in small coreless and medium iron-core sizes.

Notes on this data
SGMCS figures from Yaskawa spec sheet YEA-KAEPS800000042K, read from a distributor-hosted copy (Yaskawa's own pages render specs by script and returned no data). Still listed under Sigma-7 direct drive on yaskawa.com; no discontinuation notice found, but its OD/torque ranges match the newer SGM7E + SGM7F, which look like the successors - not confirmed. No SGMCV data found.

Typical applications
Alternatives that meet or exceed these figures
Engineers often come to us with a Yaskawa part number and leave with an alternative that is easier to source, quicker to deliver or a better fit for the machine. These 3 series from our supply network are the closest match on published figures.
Housed iron-core direct drive rotary motors with bearings and optical encoder, 110-360 mm frames, up to about 1 kNm peak at 600 VDC.
| Published maximum | SGMCS / SGMCV direct drive | ADR-A |
|---|---|---|
| Continuous torque | — | 407.2 Nm |
| Peak torque | 600 Nm | 1,017.9 Nm meets or exceeds |
| Speed | 500 rpm | 2,000 rpm meets or exceeds |
Low-profile housed iron-core direct drive motors with large centre holes and incremental encoders, 80-400 mm frames.

| Peak torque | 600 Nm | 648.9 Nm meets or exceeds |
| Speed | 500 rpm | 3,000 rpm meets or exceeds |
AXD variant with 23-bit BiSS-C absolute encoder resistant to contamination, 120-400 mm frames.
| Published maximum | SGMCS / SGMCV direct drive | AXD-ERA |
|---|---|---|
| Continuous torque | — | 250.6 Nm |
| Peak torque | 600 Nm | 648.9 Nm meets or exceeds |
| Speed | 500 rpm | 2,000 rpm meets or exceeds |
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
