Here is a proposal on how this device could produce 60hz output.Viewing the video at .25x speed, the timing of one complete cycle of the control board's leds appears to be 1s. It also appears that 2 switches are on at any one time, so this would be equal to .025s in real time with a total of 18 intervals. Therefore, each switch interval is .025/18 = 1.389ms.Calculating the total number of intervals at 60Hz is (1/60)/1.389 = 12. Since there are 36 total coils, 36/12 = 3 coils per switching interval. However, to produce an even magnetic field across the stator, 2 pairs of 3 coils each positioned oppositely from each other on the stator would be required and driven with opposite polarities. So, we have two 3-coil pairs sequentially switched on for a period of 1.389ms for a total of 12 intervals to complete one cycle which would equal 16.667ms which is 60Hz.Regards,Pm
Yes, I could be wrong with 16 Poles, maybe only 12 then ?Could you please draw up a drawing how you see it ?Well, yes as the flux lines must go out into the air and not stay inside the stator iron, he has to use some kind of trick to force the fluxlines go out into the air...So he might use 3 coils to do this, so the middle one of each pole is the one which flux lines are forces out of the core....Do you mean it like this ?Many thanks.
There are some other observations:<snip7. His arduino is from www.sainsmart.com. But Googling I can't find any reference on Arduino 2556 (I do find 2560).snip <
So PMGR? Why did you decide to snip your content?
3. I notice a thin red wire going from the diode bridge into the same bundle as the wires coming from the cap/resistor. Then a black thin wire pops up at the end of this bundle together with the red wire, but I don't see where it is coming from (maybe it is spliced into the thicker black wire somewhere).
