Product overview
The 57HSE series uses a 57mm square flange and encoder feedback for closed-loop motion control with a compatible driver. Choose the model for the load, mounting space and shaft requirements. Electrical and mechanical data for each model are listed below.

These are representative catalog models. Confirm the pilot, shaft and shaft-end dimensions for the selected model. Customization is available; the approved drawing defines the final configuration.
Dimensions and mounting
Dimensions in mm. Flange 57 × 57; hole pitch 47.14 ± 0.2; four Ø5 mounting holes; pilot diameter 38.1. Shaft diameter 8 and flat dimension 7.5. Standard shaft extension L1 is 21 ± 1; models ending in 30 use 30 ± 1, with flat lengths of 15 and 25 respectively. See the model table for body length L.
Motor and encoder wiring
| Motor phase | Wire color |
|---|---|
| A+ | Red |
| A− | Blue |
| B+ | Green |
| B− | Black |
| Encoder pin | Wire color | Signal |
|---|---|---|
| 2 | Red | VCC |
| 3 | White | GND |
| 1 | Black | EA+ |
| 13 | Blue | EA− |
| 11 | Yellow | EB+ |
| 12 | Green | EB− |
The encoder uses a DB15 connector. Verify wiring by pin number rather than connector orientation. Confirm encoder supply voltage against the driver specification; no supply value is stated in the supplied catalog.
Speed and torque
The supplied speed–torque curves were measured at 36 VDC. Running torque decreases as speed increases; holding torque is not the available output torque at every speed. Actual performance depends on the driver, supply and load.
Installation precautions
- Do not strike the shaft when installing or removing shaft-end components; impact can damage the encoder at the opposite end.
- Minimize shaft-seat vibration to protect the bearings.
- Customization is available. Confirm the model, shaft, mounting dimensions, cables and driver compatibility before ordering.
Different frame sizes in this series share representative product visualizations. Do not infer shaft diameter, pilot or body length from the images; refer to the model table and approved drawing.
