Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

There is never an 'all coils off' ....

According to Jerdee's chart, step 24 on the 36 slot scheme and step 20 on the 30 slot scheme are  all coils off.

So  my question still stands  regarding the 36 slot scheme using relays, how would you recover coil energy through high side diodes only, without any negative connection to allow current to flow?

There is always a connection to ground through one of the closed bottom relays. The BEMF voltage on a coil can be higher than the capacitor voltage, so current can still flow into capacitor.

I looked back through the last few pages, I see no chart like that.

There is never a time when 0 LEDs are on except step 0.
The first step, 2, 26, 14 are on.
step 24 (25) wraps back to the start...

that LED pattern and what's in original videos matches.
There is either an LED that's out, or a transistor that is blown so the LED doesn't have much voltage backing? or there's wires crossing in front of it that cause a shadow, but there is never a time when all LEDs are off.

So...


If there are 6 poles, energizing the south opposite any particular north... then the field is north through the center, but doesn't the magnetic path then prefer to go to the near sides, and only a vary small portion actually all the way across? 


Could this be run as a bedini with all coill north instead?


But from the rotation, and the code evalutaitons; what makes this different from any other 3-pair of n/s poles around ?  (Like morin Gerald's motor) and many other stepper motors in fans and stuff...


For experimentation I'd think you'd get a higher initial activity by activating only 1 pair at a time, and aligning the center pickup coil ... well I guess if it is cycling all the way around (which the iniital iron filings demo didn't really show to me) doesn't really matter..


But then there is a difference in the voltage from luc's setup to the original demonstration


also having the coils in series divides their current by 2 (double the resistance, double the inductance) rather than activating them in parallel...

I made a time gap (all transistors Off ) in my SIMulation with recovery diodes.  The amperage is recovered for a short while. See pic.

of how to make current and what is happening by breaking down the cycle of a generator.
