Sharing ideas on how to make a more efficent motor using Flyback (MODERATED)

It looks like a 5-band resistor with colours black (0) - brown (1) - black (0) - silver (x0.01) - brown (1%)
making it a 0.1 Ohm resistor like Luc said, see http://nearbus.net/wiki/index.php?title=File:Resistor_color_codes.jpg

I think there is more a probe x1 or x10 mixup in play here.

I think it is the CVR not being able to handle the current,and so it is showing a way higher voltage across it than should be there. Looking at the video,i can see the yellow channel is set to 500mV per division. The yellow trace is the voltage across the bucking coils. Luc says the probe is set at 10x for the yellow channel(channel 1) If the probe is set to 1x on channel 1,then he has only about 1.2 volts across his coils. Now,if channel 2 is set to 10x on the probe,and 5 VPD on his scope,then he actually has only 700mV across the .1 ohm resistor. This being the case,that is still 7 amps at around 12 volts,which is still 84 watts. That CVR is definitely not rated at 84 watts. I would say 1,maybe 2 watts at most.

Brad:

"i see around 560 watts per pulse" - that is the wrong terminology and doesn't make sense, please see my posting again.  You should quote energy per pulse to use the terminology of electronics properly.

Itsu:

Thanks, it's been so long for me that I got it wrong and I thought it was <digit, digit, multiplier, tolerance>.  I realize now how I missed a digit.  There were some neurons in my head that haven't been fired up in a long time.

560 watts of power flowing through the CVR per/during each pulse.
Whats wrong with that?

Brad,

84W yes, but only for a very short time, so we have a low Pulse repetition Frequency.

There i use a ½W 50 Ohm resistor which easily can handle the 28.8KW for the 13ns pulse every 2.3KHz.

1200 volts at 24 amp's through a 1/2 watt resistor Itsu 
I really cannot see a 1/2 watt resistor doing that. There is also a big difference in time on between yours and Luc's system. I have found that it looks like you have that current flowing through,as you see the voltage across it. But the thing is,when a resistors power value is way under the required power value,you see a higher voltage across it when there is less current flowing through it.
The resistors power rating should always be above that of the peak power flowing through it.

I am not a fan of this "bucking coils" business, for the most part I view it as doing something "alternative" just for the sake of "being alternative."  In this case when the slab of metal is between the bucking coils, the magnetic fields are mostly cancelling each other out.  Even when the coils have air between them, they are cancelling each other out.

Hi MileHigh,

I would like to understand what you mean by magnetic fields cancelling each other out when the coils have air between them?

I think that bucking or repelling magnetic fields try to push away each other, towards sideways. The closer to each other the repel poles get,
the more compressed (squeezed) the fields become and they come out from the gap towards sideways and then spread out again.

Long time ago I downloaded from a now defunct yahoo group some measured flux data (collected by a flux meter probe) on the surface of
ceramic magnets that included the repel mode between them too, see attached. (I cannot recall who uploaded it back then, unfortunately.)
In those measurements the magnets were fully pressed to touch each other surfaces when they were in repel mode. It is interesting that
the squeezed-out North fields have more than twice measured field values on the touching surfaces than the sum of the
two North field values of the individual magnets.

When there is a small air gap left between the facing surfaces, (still no entering slab of metal),  the flux from both magnets should be there
(albeit in a less squeezed form) and repel force would still be there of course between the facing cores as per the gap size would control it.

When the slab of metal approaches the two magnetically bucking cores, the bucking fields from both cores will attract the slab
(more or less equally if their fields are pretty close to each other in strength).

So how do you mean the magnetic fields cancelling each other out when the coils have air gap between them?

Thanks
