**Exact dimensions.** Every file is drawn at true size with no printing tolerance. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your printer's or process's clearance before making the part.

## Notes

- Envelope only: the outside of the motor at its published sizes. The windings, magnets, brushes and bearings inside are not drawn.
- The body is a plain Ø7 × 16 mm cylinder; the Ø0.8 shaft stands 5 mm out of the front end.
- The leads leave the back end; they and any bearing boss are not drawn (not listed).
- The name is the size: 7 mm diameter, 16 mm long. It is held by its body in a Ø7 clip or socket.
- Coreless motors have no iron in the rotor, so they turn without cogging; on small, low-power Stirling models they are used as generators or tachometer pickups.
