Effects of Recirculating BEMF to Coil

Hi everyone,

I just deleted test 15 an 16 video as I have found an error in my calculations and only just noticed it now when testing my new meter. It appears that there is a .25 Volts drop at Capacitor No. 2 then what is actually at the batteries and if we do the calculations we will quickly see that it come to the same difference I measured yesterday at 75.877 with cap circuit to 76.12 direct from batteries.

So I'm sorry to say but I was wrong and need to withdraw my conclusions.

I will let you know if I find anything more.

Hello,

please read carefully how to measure rms-values

Hi Luc.

This is precisely what I was getting around to telling you yesterday with my post at EF (first I wanted to see if you noticed the discharge rates for each). I'm glad you figured it out on your own.

I am sure that the measured voltage would slowly decrease at about the same rate in both cases, but with a 0.25V offset due to the drop across the 10 Ohm. Sorry for not mentioning it then, but I had doubts you would have been too receptive.

Hi all,

here is the status at this time in a video update.

Hi everyone,

it's been a while since I've posted. Been busy making some $ and stocking up while I can for the long Canadian winter

Tyson, user Skywatcher at Energetic Forum asked me if I had any ideas to use this effect and I said no but honestly I always had a motor in mind

So I decided to go back to my basic idea and re-tested with a simple yet effective way to see if it has any advantages in a motor.

I made a new video and I think it's simple enough that most anyone to understand. The result are quite interesting comparing a straight DC capacitor discharge to the coil and magnet with no flyback circulation vs flyback re-circulation for the same magnet lift, measured height in the video below.

The results are as followed:

No flyback circulation using a 58uf discharge cap charged at 200V = 1.16 Joules.

With flyback re-circulation using a 58uf discharge cap charged at 84V = 0.205 Joules.

That is close to 1 Joule less for the same height ... can someone please explain what I maybe missing here ... would this not be of benefit to a DC magnet motor???

Thanks for your time.
