Notes:
- 1
- Output shafts add 15 mm to the 26 mm length. See dimension diagram for details.
- 2
- D shaft.
- 3
- Typical; ±20%.
- 4
- Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
- 5
- This motor will run at 6 V but is intended for operation at 12 V.
