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

I think, that this generator work in fallowing way:

Pierre said that only six coils are on at a time, then the next six turn on just as the previous are turning off.
Doesn't that mean there could only be 3 coils at say 0 degrees, then 3 at 180 degrees?
3 at 0 degrees north, 3 at 180 degrees south?
Also the sleeve inside the motor housing, whats that for ,and what is it aluminium?
Thanks artv

also watch the first video where he inserts the magnets to show rotation, slow it down you see a very jerking motion
it seems to match up with the bulges of coils winds at 10 ,2, 4 and 8

L192, you can measure from one half of the stator to the other half of the stator. I believe you have 30slots, so you would be measuring two parallel strings of 15 inductors in series, so what you would measure would be 7.5*L and 7.5*R where R and L are for a single coil. So no need to disconnect anything. Just make sure the rotor is not in the stator.

Hi PmgR,

Each coil is 1.42 ohms and 1.176mH  without rotor present in stator.

Hi Shylo,

Pierre's diagram shows 6 coils energized in series for each pole, so that's 6 x 6 = 36 coils energized all the time.

Its the poles that rotate by changing the high side and low side switch pairs, in a one coil per step sequence, combined with a 1 coil overlap to ensure the magnetic field is never switched off.

Hi listener191,


I think 12 coils all the time for 36 coils stator.

section from 1 coil sets (6 coils)...
section from 2 coil sets (6 coils)...

=12 coils all the time.
