53 OHMS OF 30 GAUGE WIRE IS STILL HIGH IMPEDENCE - I BELIEVE HP'S EFFECTS ARE SIMILAR TO STEVE'S (CORE SATURATION RESULTANT ACCELERATION). MY MISTAKE WAS ASSUMING LAMINATED CORES REQUIRED HIGH #'s OF TURNS AS DID IRON CORES.

Assume nothing !

BTW the gap between the rotor magnets and stator cores are .4 of an inch on average or there abouts.

I do not have any back iron but the 2 cores are close together with just enough room to put 2 folds (4x thickness) of paper between the 2 transformers so it is pretty good.

Putting back iron with a gap as large as in Thanes test would not significantly increase the magnetic coupling.

But the back iron might be helping out in some other way.

With coils as low as 53 ohms I am wondering if maybe I should wind a coil on the I core pieces.

Still I would far far rather Thane just send me that coil he tested for me. (I would only ask that whatever is sent works with a 6 pole rotor with a half inch gap at 400-500rpm)
If I can get a coil that I know will work I'd be really happy.

Has there been a coil made with all laminated steel (ONLY professional laminates none of those metal strips) that has worked?  Or have ALL of the laminated tests that have worked had other metal near by?


If you send it right away it might just arrive in time for my 30th.

YOU MEAN YOU HAVE HAD NON-POOR ATTEMPTS?
WHEN?
ON THIS THREAD?
WHERE?
CAN I READ ONE?

THANKS

I DID TEST THIS A FEW PAGES BACK (PAGE 48) WITH THE SPLIT-PHASE MOTOR TEST.
HV ACCELERATING COILS REQUIRED LESS MOTOR INPUT POWER THAN WITH NO COILS AT ALL.

For some insight into these results, check out this torque-speed characteristic of a typical induction motor:



At most points of the curve (take for example the 70% point), the torque increases while the speed also increases and the input current drops. The increased torque allows the system to drive the additional drag of a shorted or loaded coil. Higher load, higher speed, lower power input.

DEAR ALL,

PLEASE FIND ENCLOSED

1A - NON WORKING COIL - TOO MANY TURNS MOST LIKELY.

2A - 2 WORKING COILS ON THE SAME CORE - LESS TURNS.

3A - HC COIL SHORTED CURRENT MAGNITUDE

AND A COUPLE OF THE CHEEZEWIZ BUGGY.

CHEERS
