| Rated torque (catalog) | 6 N·m | 3.3 N·m |
| Maximum speed (catalog) | 600 rpm | 383 rpm |
| Mass | 485 g | 507 g |
| Gear ratio | 6:1 | 6:1 |
| Voltage | 24-48 V | 10-44 V |
| Price (catalog, not a live quote) | 470 USD | 879 USD |
| Encoder (resolution is not accuracy) | 14-bit magnetic (motor-side) | on-board magnetic absolute |
| Complete actuator efficiency | Unknown: not documented | Unknown: not documented |
| Cooling / thermal duty | Unknown: not documented | Unknown: not documented |
| Loaded repeatability | Unknown: not documented | Unknown: not documented |
| Calibrated simulation model | Unknown: not documented | Unknown: not documented |

Sensor bits do not establish loaded accuracy. CAD geometry is not a calibrated simulation model. Verify thermal conditions, duty and exact revision before engineering use.

Catalog photo; illustrative. Confirm hardware revision/variant.

Catalog headline specs spot-checked: confirm revision. The legacy verified flag is a catalog spot-check, not verification of every field, installed revision or independent performance validation. Catalog entry only; confirm the exact revision and operating conditions with the linked source.

## Arithmetic from catalog values

Differences are subtraction of retained catalog values, not measured advantages. Ratings may have different test conditions. Unknown means not documented; manufacturer claims and catalog spot-checks are not independent validation.

- Peak torque: AK80-6 (KV100) (12 N·m) minus qdd100 beta 3 (16 N·m) = -4 N·m.
- Rated torque: AK80-6 (KV100) (6 N·m) minus qdd100 beta 3 (3.3 N·m) = 2.7 N·m.
- Maximum speed: AK80-6 (KV100) (600 rpm) minus qdd100 beta 3 (383 rpm) = 217 rpm.
- Mass: AK80-6 (KV100) (485 g) minus qdd100 beta 3 (507 g) = -22 g.
