I was thinking about each individual winding, not bullet to bullet. There are two windings per phase in series (four poles) and two phases in series due to the wye.

The IO current is at 10V -- I'd have to measure it at 32V.

Sorry!

OK. So the Ri of one winding is 170microohm (!) or 1.7milliohm (more realistic) ? It would give 3.4milliohm phase to phase and around 4.4milliohm bullet to bullet and it's seems pretty realistic for a motor of that configuration and size (one turn WYE and 1230 grams) ?

That's about right, including the wire and bullets.

OK. Do you have the possibility to measure the I0 at 32V ? It would be great ! TIA.

And do you know the maximum allowable current in the 2028 winding before the iron saturates and so the torque does not scale linearly with the current and the efficiency rapidly colapse ?
