| Maximum speed (catalog) | 310 rpm | 320 rpm |
| Mass | 521 g | 375 g |
| Gear ratio | 10:1 | 8:1 |
| Voltage | 24-48 V | 24-56 V |
| Price (catalog, not a live quote) | 399 USD | 129.2 USD |
| Encoder (resolution is not accuracy) | 14-bit magnetic (motor-side) | 16-bit |
| 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: AK70-10 (KV100) (24.8 N·m) minus GIM8108-8 (22 N·m) = 2.8 N·m.
- Rated torque: AK70-10 (KV100) (8.3 N·m) minus GIM8108-8 (7.5 N·m) = 0.8 N·m.
- Maximum speed: AK70-10 (KV100) (310 rpm) minus GIM8108-8 (320 rpm) = -10 rpm.
- Mass: AK70-10 (KV100) (521 g) minus GIM8108-8 (375 g) = 146 g.
