Bedini 1984, 2017 style.

So from the data at top speed we can conclude for an 8 x 18ga Standard Bedini coil in series.

* At magnet spacings of 53mm the coil/magnet saturates resulting in reduced voltage output across the entire spectrum.
* At 16metres per second the coil puts out an average of 116V pk-pk.
* Motor current reflected only aerodynamic losses.

Test Data on an 8 Filar 18ga Bedini Spec coil in series.
18 Magnets, North Out.
Magnets spaced at 53mm saturate. At 106mm appear to correlate with other arrangements.
Further experiments may hone in on the perfect distance but this wheel is not designed for those experiments.
When possible I will run with an 18 magnet wheel.
Curiosly Rick's 10 Coiler runs at 67mm with smaller Neo's.

Just putting some finishing touches on some super poles to fit to the wheel.

Question.
I've seen a lot of mention about double and triple stacking of rotor magnets to amplify field strength.
I have enough magnets to be able to build one stacked configuration.

What is the best stacking method you have tried? ie how many, in what orientation and direction.

Comparison's of different combinations all at 490RPM's
The 36 magnet wheel has the higest frequency but the lowest pk-pk voltage.
The 18 magnet wheel appears to be the right blend for this size wheel and magnet.

Test Data on an 8 Filar 18ga Bedini Spec coil in series.
Stacked Super pole magnet facing north out with both souths glued together.
Results were less than impressive. I used one stacked super pole and one North out magnet to offset weight on wheel.
The peaks are the standard North out.

Test Data on an 8 Filar 18ga Bedini Spec coil in series.
Stacked magnet facing north out with NS glued in middle.
To offset weight on wheel I once again used a standard 2"x1"x1/2" with north out.
The results are fascinating, indistinguisable between each other.
I used a gauss meter to test the north face and measurements were identical.
Conclusion stacked magnets will produce the same result per mass and geometry as a single magnet.

To make sure the stacked magnet wasnt a static potential I ran North out with a single 2" x 1" x 1/4".
Numbers run well under.

Excellent basic research here John - results put the gen coil and mag configuration in the proper perspective. Big Thanks for sharing your work, presentation and experimental results.

This is stepping up the depth of the magnet by 1/4" increments.
Starting at 1/4 - 1/2 - 2X1/4 - 3/4.
Ill have the data on a double stack 1/2" shortly but the trend is positive.
Smaller narrower magnets stacked NSNSNSNS will give greater depth of field and higher coil potential.
There is a small increase in wheel diameter and perhaps speed but cross referancing the velocity to matching numbers still gives a higher voltage.
