Mostly Permanent Magnet Motor with minimal Input Power

Hey Luc
So you reduced the input voltage for the parallel test as compared to the voltage for the series test to come to a common watt figure?

Mags

When compared to running a single coil:

When the coils are in parallel, the resistance of the circuit is basically cut in half (increasing current flow), and likewise when the coils are in series, the circuit resistance is nearly doubled (reducing current flow). 

As far as I have been able to determine, whenever a coil is used directly in a motor, it acts as a generator and limits performance to under unity, due to the generator effect.  (The better the magnetic coupling, the better the efficiency, but it also increases the generator effect limiting performance to under unity).  The device does appear to be a good way to increase magnetic coupling.

Yes Liberty, you are saying the same thing that I have already posted: http://www.overunity.com/8429/mostly-permanent-magnet-motor-with-minimal-input-power/msg418431/#msg418431

Luc,

You can make major improvements to your efficiency test.  Can your setup move up one centimeter instead of one millimeter?  You can't eyeball a 1/2 millimeter height increase with more than say +/- 15% accuracy.

I am going to assume that you can do a one centimeter jump up as the basis for the test.  Then all you have to do is adjust the voltage on your capacitor until the jump up is one centimeter.  If you do this properly where you watch a marked reference line on the jumping Super build and see if it comes into alignment with an external reference line that indicates a one centimeter height increase, you should be able to eyeball this to +/- 2% accuracy.  You just have to experiment with different voltages on the capacitor until you find a voltage that causes a one centimeter jump.

Of course when you calculate the the amount of energy in the capacitor it will be larger than the energy required to make the one centimeter jump.  So where did that energy go?  That's all part of the analysis of the experiment.  You should be stating this stuff as part of your conclusions.  I can think of two places right off the bat that would most likely account for most of the lost energy.  Can anybody else?

If you do choose to do this improved experiment then I challenge you to actually report your calculations, including your estimate on the error tolerance, and how you actually estimated that error tolerance.  You didn't follow through on the previous attempt.

Meanwhile my previous challenge to everyone about the issues with the tracking of the variables for the main tests remains ignored.  The more you put into your experimentation, the more you get out of it.

Hi MH,

to raise the 2.325kg coil up 10mm the 7170uf cap bank needs to be charged to 9.3vdc = 310mj

I'm sure these solid steel cores are a cause of some loses

I'll add that the test above was with the coil connected in bifilar Series since when it was connected in Parallel it needed a little more Joule energy.

So to raise the 2.325kg coil up 10mm

Coil in Series with 7170uf cap @ 9.3vdc = 310.07mj

Coil in Parallel with 7170uf cap @ 9.9vdc = 351.37mj
