I think that it stays proportional....which means yea, it'll get worse...i.e. more wasted currents...
I have no Idea how the distributed affects things...yet...
I don't think it matters loaded or unloaded...But I'm not sure of that.
There are only a few things I am sure of....death, taxes, and I like warm fires...
I'm referencing Dr. D Hanselman's book, BLPM Design, for the 22% figure in the earlier post.
But the recirculating current problem is well known.
Dr. H has some tables in the examples chapter that show "Phase Back EMF HArmonic Amplitudes Relative to the Fundamental".
For the 24 Slot, 8 magnet configuration like the Astro.
The 3rd Harmonic is 22 or 23%
The 5th is ~8%.
For the 12 Slot, 14 magnet configuration of the Turnigy
The 3rd Harmonic is 10%
5th is negligible.
For large slot motors...I'll just pick an example (apparently a good one!)
36 slot, 24 mag,
3rd H, 1%
THis may be why the Turnigys run pretty good in Delta and probably alot better in Y.
I think I'll convert the Turnigy in Y to eliminate some "dead currents" and get some halls sensors on there as well.
But, you may have to have the Astros in Y and only Y.
If anybody want's me to look up some stuff, just send me the config and I'll reference Dr. H's book.
