Simplicity
Sometimes you just have to go back and reread your own logic. These forums act as a sort of journal and that allows you to go back and recheck your past thought processes. In retrospect my thinking about Single Phase this last winter was really good. The "push pull" advantage in the wiring is enough to make it a preferred choice over Three Phase. (it literally cuts the kv value in half)
Here's an image of Single Phase. The colors are defined so that anything OVER 1 Tesla is in purple, so you can see how the magnetic flux lines flow:
...0.5 Tesla magnets end up generating a 1 Tesla magnetic flux at the point of interface with the cores and inside the cores the flux rises to 2 Tesla's which happens to be the limit of Silicon Steel cores. (saturation) So if I really want to max out the design the use of Single Phase is in line with optimal results.
The bottom line is that I can pack things a lot tighter with Single Phase.
I was hoping that Three Phase would be equal, but it ends up doubling the kv over Single Phase.
---------------------------
It's kind of like deciding between a two stroke and a four stroke gas motor... I know from the past that two strokes dominated, but in the end the benefits (pollution reduction) of four strokes won out. From a pure performance standpoint the Single Phase is like a two stroke.
