My E-motor - how does it work?

[gravityblock]

@Seth,

Did you read the publication in my previous post on the Electrostatic Swing Energy Harvester which uses a homopolar electret? Could this publication provide useful and beneficial techniques, so your e-motor will operate at much lower voltages and higher rpm's. Just a thought.

Thanks for the links GB They look really interesting and i need to spend the day slowly taking in the new info. Making my own electret sounds like a lot of fun and could indeed prove very useful.

I think Professor Turtur managed to use an electret (i think he just used a balloon) to turn a rotor a couple of revolutions - not much, but a start. Check this out

In order to approach to this goal, the field source was replaced by an electret, which does not enable electric currents in the
range of pico-amperes (or more). The electret which was used, was a balloon filled with air (as children use for playing). This
material was rubbed on its surface until its electrostatic charge and potential was enough to keep the balloon at the bottom
side of ceiling of a room against gravitation. Thereafter the balloon was positioned (by hand) above the rotor as field source,
and it made the rotor spin, but only for one or two (not more than two and a half) revolutions. The rotation of the rotor
stopped when the rotor came to a minimum of energy. The rotation did not run out continuously, but it stopped because of
electrostatic forces, and sometimes the movement could be restarted for another half or one revolution by moving the
charged electret-balloon a little bit. This indicates, that the charge on the surface of the balloon was distributed rather
inhomogeneously. This inhomogeneity of the charge distribution is confirmed by the fact, that the balloon turns itself to an
energetically minimal position when being brought into contact with the ceiling.
The observed movement (of not more than three revolutions) is not enough to claim, that a permanent rotation for the
conversion of vacuum-energy was already generated with an electrically charged electret, but it is enough to exclude, that
the effect of electrostatic rotation is caused by the Biefeld-Brown-effect or by some electrohydrodynamic reasons, because
there is no electric current and thus no conventional electric power driving the rotor, with the field source being an electret.

Ive just done a couple of experiments which leads me to believe this isnt ONLY a simple homopolar motor (as Jetijs recognised), nor just an ion thruster. Correct me if im way off the mark guys, but.....

a) homopolar action will only work with DC - the e field must be in a continuous vector or else the force would go back and forth and cancel itself out. So, AC wont provide any thrust on my setup

Well, ive just tried my setup on the transistor/flyback circuit - im pretty certain the output must be AC. And even when i only connect ONE electrode to the rotor - it spins, PROVIDING THAT there is a sheet of Al foil connected to ground. It spins even faster if the Al foil is connected to the other HV output wire......so why does it spin on AC???

So, perhaps this is just an ion motor. But then it would spin without the sheet of AL foil. Any nearby object would aid the ion thrust mechanism. Nonetheless, this ISNT the case with my setup. It wont spin without the Al foil underneath and grounded - so i conclude that it isnt just ion thrust either.

It seems to me theres something else here.

Please point out any clear mistakes in my logic if there are some - im here to learn.


OK - ive played a bit more and changed my mind!!! The Al foil increases ion thrust. nothing more.....Thats why it works with but doesnt work without.

What kind of flyback are you using? Is it something like this:

If yes, then the output of it is DC, because these types of flybacks have internal diodes in them.

Thanks for putting me straight Jetijs - like i said, im here to learn!

Should have realised my mistake - i think even my GCSE physics teacher told me many years ago that a cathode ray tube was pulsed DC.
