Re: Self Looped Cap Dump Bedini Motor

Unfortunately, those authors theories remained theories.  For me, the zero force motor, for instance, was a disappointment in the moment Peter Lindemann wrote this:

   "In this machine, Lenz's Law is FULLY OPERATIONAL, as is Ohm's Law, Kirchhoff's Law, Faraday's Law of Induction, and Newton's Third Law of Motion."   

Quoted from this post:     https://www.energyscienceforum.com/forum/alternative-energy/john-bedini/1861-zero-force-motor-replication-project?p=35986#post35986 

Here is one of the efficieny tests done by Yaro on his zero force motor build, (he made two presentations on Aaron's Energy Science and Technology Conference in 2017 and in 2018):

Gyula I can see how that comment, by Peter would take the wind out of your sails. I must apologize as maybe I have not been to clear Lenz's law cannot be done away with in DC permanent magnet motors, it is common place to see the CEMF reducing the current when a DC PM motor is running at its no load speed. When we load the shaft, at no load speed, the motor will produce less CEMF allowing for more current to be drawn under load. This is because the motor physically does not generate as much when you slow it down, so you have less CEMF countering your applied voltage. This is Lenz's law.

Are we in agreement with this so far or am I mistaken?

Hi David, 

Yes, I agree with what you wrote on CEMF behaviour in DC PM motors, pulse motors, where normal induction happens invariably in the coils caused by the rotating PMs and the induced voltage opposes the input emf. 
  Another manifestation of Lenz law is when you connect a voltage source across a coil and current is delayed 90 degree wrt the voltage by the self inductance of the coil.   Or a loaded coil is induced by a changing magnetic field and the induced current's fields works against the inducing field. 

I mentioned the zero force motor because it had been kept in secrecy for long, no details were given and was said to be a no Lenz, no back emf motor by JB, very likely due to the not correct theory associated with it.

This image of a magnet is from the work of Howard Johnson, it shows the magnetic spins of a magnet.

Here is a scope shot of my pulse motor. This measurement was taken back in March of this year using a Hantek AC/DC Current Clamp CC 65

Interesting video... thanks for sharing.
