AC voltage from single magnetic pole

Good morning PM.


Nice clear test.  I do have one question.  What is your load?  If the left coil is the current sensing coil then what is the load it is connected to?


Thanks,
Carroll

Hi Carroll.

I'm seeing a short " Yellow jumper " shorting the coil with the Current probe attached to it.

Cheers Graham.

Hi Graham,


I see 3 ends to some yellow jumpers so I am not sure what is connected to what.  My eyesight is not too good right now.  I have got to have cataract surgery soon.  Thanks for your answer.


Take care,
Carroll

If you're getting cataract surgery, astaxanthin is a must, in fact, it's a must in any case.

Get natural not synthetic.

Carroll,

The only load to the center coil is the shorted coil on the left and it's dc resistance.  The coil on the right is of course open with scope probe load of 10M ohm and 3.9pf.

Here is a scope pix of the 3 coil layout with a 2 pulse input to see the phasing from a zero electromagnetic start rather than continuous running periodically.

The specs on the coils are as follows- L1,L2,L3 = 746uH.  L1+L2 = 1.509mH, L1-L2 = 1.385mH, therefore the coupling K = .0415 between adjacent coils as pictured. 

The formulae used to calculate the k factor are M=((Lseries+)-(Lseries-))/4 and k=M/(L1*L2)^.5  .
