Confirming the Delayed Lenz Effect

[CRANKYpants]

My replication should be ready within a day or so, for now: a little teaser of my new setup.
24 magnet poles, 20 generator coils, almost no cogging.

DEAR kEhYo77,

R. BUCKMINSTER FULLER ONCE SAID, "EVERYONE IS BORN A GENIUS, BUT THE PROCESS OF LIVING DE-GENIUSES THEM."

NICE TO SEE YOUR DESIGN GENIUS HERE ALONG WITH ALL THE OTHERS!

DEAR kEhYo77,

WHAT IS YOUR CORE MATERIAL?
(I HOPE IT IS NOT METGLAS OR FERRITE?)

IF YOUR MAGNETS ARE ALTERNATING N-S-N-S ON THE ROTOR YOU WILL ONLY GET POSITIVE RESULTS (ie increased on-load EMF as mentioned in post # 360) FROM YOUR COILS THAT ARE PLACED ON THE SAME POLE POLARITY IE ALL NORTH POLE MAGNET POSITIONS OR ALL SOUTH POLE.

KEEP ALL THE CORES THERE THOUGH SINCE THEY BALANCE AND REDUCE START-UP COGGING - HOWEVER COGGING DIMINISHES WITH RPM ... SO YOU CAN PULL THE NON USED CORES OUT (IF POSSIBLE) TO REDUCE HYSTERISIS LOSSES IN THOSE UNUSED CORES ONCE YOUR SYSTEM IS UP TO SPEED.  GOOD LUCK!

I already achieved acceleration with those ferrite cores and the 4 coils in the picture are all on the same phase (the same pole is facing them simultaniousely in NSNS config) and there are 5 phases like that. The plan is to change the core material later on to see the difference.

Thanks for kind words, Thane.

Hi Thane

So i do suppose that if we can arrange a setup with perhaps an odd and even repartition of coils and magnets (for example 16 magnets on the drum and lets say 7 coils ) in order to reduce the cogging at minima, we could get something  usable...........really interesting. Hmmm!!

Good luck at all

DEAR LAURENT,

MY SUGGESTION IS THAT PEOPLE ELIMINATE THE EXTERNAL PRIME MOVER AND USE THE GENERATOR COILS AS MOTOR COILS TO GET THE SYSTEM UP TO SPEED AND THEN CONVERT THE MOTOR COILS OVER GENERATOR COILS INDIVIDUALLY ONE BY ONE.

THIS IS A GOOD PLACE FOR MOTOR MAKERS TO START: http://www.simplemotor.com/hemotor.htm

THIS WAY THERE IS NO COGGING TORQUE WHICH NEEDS TO BE BALANCED.

DEAR kEhYo,

NO DOUBT ABOUT IT - YOUR MACHINE IS A THING OF BEAUTY!
HERE'S TO HOPING IT IS MORE THAN JUST A PRETTY FACE... 

I HOPE YOU KEPT YOUR CUTTING TEMPLATES, PEOPLE MAY WANT TO BUY SOME "KITS" FROM YOU LATER ON.
