**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 can is Ø27.7 × 32.6 with a Ø10.0 × 2.6 boss on the front face and another on the end cap.
- The Ø2.3 shaft runs 15.6 mm out from the front face on the 365 and 11.6 mm on the 360; the cans are the same. The drawings' overall lengths (51.0 and 47.0) are 0.2 longer than the drawn parts.
- Two M2.6 × 0.45 tapped holes on 16.0 mm centres in the face, drawn at the thread's major diameter as deep as the usable screw length on the drawing (3.0 on the 365, 4.0 on the 360).
- Vent holes, terminal tabs and the wire exit are not drawn.
- In DIY Stirling builds, brushed DC motors of this kind are turned by the engine and used as a generator (an LED, a resistor or a meter across the leads) or as a load on the flywheel shaft.

Ø27.7 × 32.6 mm can, Ø2.3 shaft 15.6 mm from the face, Ø10.0 bosses 2.6 tall front and rear, two M2.6 holes 16.0 apart.

**365 vs 380 motor?**

Same Ø27.7 can, boss and M2.6-on-16 face; the 380 can is 37.8 long instead of 32.6.

**What screws fit a 365 motor?**

M2.6 × 0.45 into the face, no deeper than 3.0 mm into the motor on the 365 (4.0 on the 360).
