Bedini SG notes

[Farmhand]

Here's a video clip of a very hastily put together demonstration using a universal motor powered by a 12 volt battery
and a DC to DC converter (boost converter), the motor coils are switched by mosfets so that they discharge into a capacitor.
The video shows that when the motor is made to accelerate by applying more voltage/power then the coils discharge is less
and the capacitor voltage drops, however when the rotor is slowed by hand "a mechanical load" then the coils draw more power for each cycle because the frequency is lowering and the coils impedance is diminished as well allowing more current and correspondingly the capacitor voltage rises.

Please keep in mind this video was never mean't to be anything more than a demo to show another experimenter.

Coil recovery experiment.

in that situation energy in the rotor is reduced and the capacitor voltage goes higher.
In the former situation the energy in the rotor is increased and the capacitor voltage is reduced.
All seems to be in order nothing out of the ordinary, it is as expected.

When energy is increased in the rotor it takes away from the amount of energy the coil has left to discharge.
When energy is decreased in the rotor it leaves more energy for the coil to discharge.

This is an important factor that is denied or ignored by many Bedini fans.

It is interesting to note, that while the current flow direction remains the same in the inductor through the on/off cycle,the voltage is inverted when the inductor switches off..So could this be the thinking behind the back EMF to forward EMF switch?.

Another good build,is to use electron flow,insted of conventional current flow. For this you will need a pnp transistor,and im sure you can all work out how to wire the rest of the circuit up.

Then you can merge both together
See if you can work out how to get an inductive kickback from both directions,using onlyone single run coil.

It all depends on how you define the terms and definitions doesn't it.

Counter emf, Back emf, are they one and the same to you or is Back emf the coil discharge and counter emf the Lens drag,
or is Back emf the Lens drag and the coil discharge is just a coil discharge.

To me Back emf and counter emf are one and the same, the coil discharge is a coil discharge and is forward emf which faces it's
own counter emf produced in the wire when it discharges.

The coil discharge can be called "flyback" or whatever, but why mix it is with counter emf by calling it back emf ?

A coil can discharge from either or both ends yes.

I still say my idea of feeding the coil discharge back to a charging circuit which helped turn the rotor and increase the voltage for the main motor coil was a more complete way to utilize the coil discharge to turn the rotor. Being that the rotor seen two
separate driving phases the torque was increased significantly.

The main point of the video experiment was to show that when a motor is made to accelerate the rotor there is less energy left
to discharge from the coils.

And when the rotor is made to slow down by a mechanical load there is more energy left to discharge from the coils.

While adding energy to the rotor the coils consume more of the energy they take up and less is left to discharge, this is direct evidence that the mechanical work is not free as John claims.

While taking energy from the rotor with a mechanical load the coils have more energy to discharge. This backs up the assertion
that the turning of the rotor consumes energy and so the mechanical output from a Bedini machine is not free.

Tinman I can't get what your doing without a drawing.

Regardless the coil can only discharge the energy it takes in, it cannot discharge energy it does not take in.
All the energy taken in by the coil originates from the supply. No one has given any proof as to otherwise.

Why do so many people want to mix terms ?
