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 | SGM7D / SGM7E / SGM7F direct drive | ADR-A |
|---|---|---|
| Continuous torque | — | 407.2 Nm |
| Peak torque | 600 Nm | 1,017.9 Nm meets or exceeds |
| Speed | 600 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.
| Published maximum | SGM7D / SGM7E / SGM7F direct drive | AXD |
|---|---|---|
| Continuous torque | — | 250.6 Nm |
| Peak torque | 600 Nm | 648.9 Nm meets or exceeds |
| Speed | 600 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 | SGM7D / SGM7E / SGM7F direct drive | AXD-ERA |
|---|---|---|
| Continuous torque | — | 250.6 Nm |
| Peak torque | 600 Nm | 648.9 Nm meets or exceeds |
| Speed | 600 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.
