F4P's 144mm low rpm Outrunner

[F4P]

omg...what a chaos. thanks for the tipp.

[pre]torque 0,7285 1,457 2,1855 2,914
eta conductor losses 0,183 0,736W 1,655W 2,94

iron losses rpm / Current 1 2 3 4

7,00W 600 84,22% 91,55% 93,70% 94,57%

8,56W 700 83,52% 91,30% 93,62% 94,61%[/pre]

i hope it's a better now with only the relevant values. the table is to complex to be added completely. Main point is still 7W Iron vs. 0,7W conductor losses. Would it help to reduce the number of poles or will it bring up other disadvantages?

The "problem" seems to be simply the low torque requirement

Fewer poles will mean more material needed for rotor and stator yokes. Also, fewer possibilities to maintain cogging frequency.
